Hunting trailer type – what to build

What trailer type or trailer styles suit towing quads, side by sides and motorbikes? There are two trailer types we will look at; tandem trailers (car trailers) and flatbed (table top) trailers. I’m sure the different trailer types may be known by other names in different regions.

Tandem trailer

A tandem trailer has dual axles with the wheels outside the deck area and the deck is below the mud guards just like a car trailer (for towing vehicles). This makes the tandem trailer quiet wide, generally as wide as the maximum width of 2.5m as per the ADR.

They tow very well and have a low centre of gravity. Loading quads sideways over the guards is difficult to put ramps on and can cause damage to the guards.

Some people build platforms spanning the sides for the quads to sit on top of the trailer to make it much easier to load them on (negating the benefit of low centre of gravity).

The video above demonstrates the issue with the wide axle trailers in mud. When the roads are rutted and the surface is slippery the wheels naturally want to ride in the wheel ruts. Causing the wide axle trailer to dive from side to side as the tandem axles become crocked.

This zigzagging of the trailer causes the trailer tyres to pickup a lot more fresh mud clogging up the guards, causing the trailer wheels to skid pulling the tow vehicle to a halt. Now you have to get out of the car every couple of kilometres and dig the mud out.

The zigzagging also pulls the back of the vehicle around making it very unstable and difficult to maintain a reasonable speed. Several times we were nearly pulled into the table drain because of the trailer.

Not my preferred trailer type. I’ve experienced the above on 3 trips which is what prompted my trailer build and this article.

Flatbed trailer

A flatbed or tabletop trailer with dual axles has the deck over the wheels. This means the trailer is narrower than a tandem trailer and the deck is higher.

Having a flatbed trailer with the same track (axle width) as the tow vehicle is so much better off-roading. It doesn’t collect as much mud, stops it swaying from wheel rut to wheel rut and cant collect obstacles past the edge of the vehicle.

Flatbed trailers are no more difficult than loading the tray of your ute. As with tandem trailers they tow very well. Not having mudguards makes them a lot easier to use ramps and load quads sideways.

They are far less prone to damage with less protruding parts and safer for overtaking for those mates that “forget” the trailer is attached and is wider than the ute.

Trailer type recommendation

After towing a car trailer and tandem axle box trailers on several trips I would never own one for hunting. A table top trailer is the only way to go. Safer in the mud, easier to load quads onto and you don’t have to worry about it clipping stuff.

Perfect Hunting Trailer Wheels

10x6 box trailer with dual axels and 4x4 offroad tyres and wheels

Trailer wheels and tyres

There are 2 easy options for trailer wheels; standard Ford Falcon style rims (same stud pattern as 2WD Hilux) with light truck tyres and 4×4 rims and tyres that match the tow vehicle.

Of course there is everything in between but these are the realistic choices as we discuss in detail below.

photo of tandem trailer with falcon rims and tyres — Ford Falcon type rims with load rate tyres to suit trailer wheels for 2000kg load limit

Ford Falcon style trailer rims

The reason I say Ford Falcon style rims for use as trailer wheels is because this is the most common stud pattern for trailers and a very common rim on passenger cars.

Ford Falcon rims are smaller width and take a smaller overall size tyre, this will lower the deck height of the trailer significantly.

Keeping the deck height lower to the ground makes the trailer easier to load and lowers the centre of gravity making it safer to tow.

Light truck tyres are cheaper and easy to obtain than bigger 4×4 off-road style tyres. Having cheaper trailer wheels means you can probably afford to have multiple spares.

Clearance of the axles on a trailer is not as much of an issue as you would think. 2,000kg tandem trailer axles are 45mm square, which is approximately 2/3 of a 4X4 diff. Trailer axles also do not have a differential pumpkin hanging down from the centre of the axle, creating a lot more clearance.

4×4 style trailer rims

Trailer wheels that match your tow vehicle are great in that you can carry extra spares across the vehicle and trailer.

Having 4×4 off-road trailer wheels however will raise the deck height of the trailer and center of gravity. The tyres will cost you more and if your they are not standard sizes you may have difficulties buying spares when your way out west.

4×4 wheels that do not match your tow vehicle are a waste and you might as well have Falcon rims. Which bring me to the point; if your going to use the trailer on another vehicle and it has different size tyres, then you have voided the benefits of matching tyres.

Trailer tyres

Just like your ute there are lots of tyre options out there. For a really good read on bias ply vs tubeless radials for off-roading read this article by Beadell Tours.

I’ve done a lot of research on the best tyre options for hunting. A very common search result is “Best tyres for roo shooting”. What you’ll find is that for “roo shooting’ the best tyre is a bias ply light truck tyre with aggressive tread such as a MRF M77.

The reason roo shooters choose a bias ply tyre like an MRF M77 is because they have a very thick side wall and very resistant to being stacked. When your constantly driving through sticks and rocks like roo shooters this is a constant problem.

However, these types of tyres are very expensive ranging from $250 – $360. I found the cheapest place to buy these types of tyres was out west like Goondiwindi (I’m from Brisbane).

I spoke at length with 2 tyre shops, they both recommended bias ply for roo shooting. However they said that they are horrible on the highway due to being a heavy tyre and the tread patterns. Both agreed that they basically just melt on the highway, expecting only 20,000km out of a set vs 50,000km from tubeless radials. For ride, comfort, longevity and cost tubeless radials are easily on top.

The trailer is not for roo shooting, it’s going to be used 90% of the time on the highway. So really you only want highway tyres. The trailer is only being pulled so mud tyres are no advantage (they cannot spin to clear the grooves either).

Trailer wheels recommendation

I’ve change my mind several times on wheel choice for a hunting trailer. But sticking with my purpose of use the decision is easily made.

Ford Falcon rims would be my preferred option for a trailer wheel. But for me it will come down to cost and the fact that I will be using the trailer across different vehicles with different tyre sizes.

The tyres I would choose would be a reasonable tubeless radial light truck tyres. They are cheap, great on the highway and mostly only used on roads. Once I get to my destination the trailer is unhitched and not used until the return trip. Just make sure they are rated to the load limit of the trailer (ie 2000kg = 4x 500kg tyres).

Perfect Hunting Trailer Finish and Accessories

Let’s look at the trailer finish and trailer accessories that will improve it’s use. I’m not going to cover legal requirements such as lights and mud guards, please check your state regulations and ADR’s.

Trailer coatings

Galvanized vs painted.

Galvanizing a trailer will add an excessive amount of weight to a trailer. Galvanizing is a must for boat trailers or anyone living along the coast. The galvanizing does give you a very strong protective coating. But as soon as you make any modification to the trailer (grinding or welding) the benefits start declining as zinc paint is not the same quality.

Powder coating a trailer is another good option. Just about every Hilux and Landcruiser steel tray is powder coated and you can see how well they last.

Trailer extras

Some extras to consider putting on your hunting trailer discussed below. Keep in mind that you want to keep your GTM as low as possible, so consider only adding what you need and not what you want (purpose of use).

Stone protection

A trailer behind a vehicle on a gravel road will just get sand blasted. Not only that, but projectiles bounce off the trailer and onto the rear of the vehicle. Sometimes smashing rear windows or in our case covering the dogs in large chunks of mud lol.

This is why it’s important to have a stone guard on the trailer. On our last trip we lost the plastics off a two wheeler from getting smashed by gravel and mud for 300km.

As well as a stone guard you can use 3 semi-trailer truck mudflaps or a single piece of rubber across the back of your tow vehicle. This should significantly reduce the amount of projectiles coming from the rear of the vehicle.

Spare wheel carrier

Consider putting at minimum 1 spare trailer wheel on the trailer. However, I think 2 spares is best on big trips. An easy option is on the draw bar, but you can always fit an under tray style spare wheel bracket like a Hilux one cheaply and this reduces draw-bar weight.

Fuel and water storage

when taking quad bikes etc. you can’t have to much fuel or water. Most 20L plastic fuel containers are 180mm (I personally own Pro Quip) allowing you to fit 10 in a row just in front of the head board on the draw bar. Once again be mindful of the draw bar weight when considering this.

Note: Fuel is about 75% the weight of water and diesel is about 83% (sourced from www.quora.com).

Recovery points

Is there a chance you may need to pull the trailer out backwards? Maybe a rear towbar or a pair of recovery points could be installed during the build.

Spares storage

Bearings, grease, dust caps, rags and tie downs should always be on board a good trailer. Under tray tool boxes would be a good option for storing this kind of stuff without increasing draw-bar weight.

Try not to buy one that hangs to low, especially if your using Ford Falcon trailer wheels.

Shock absorbers

This is more of an issue were you don’t want to bounce the contents of what’s on the back, such as a caravan or camper trailer. Also with load sharing roller rockers the axle movement can reduce some of this requirement. By not fitting them you are significantly reducing the overall build cost at no real gains.

Trailer plug

What’s standard for your state/region? What have your mates got? In the past Queenslanders always used a round 7, but this has been slowly changing to a flat 7. Adapters are available so it’s not a major issue, just have a look around before you choose.

Trailer sides

If your going to use the trailer for other activities this is something you may wish to install. But with the current tie-down laws it doesn’t have the benefits it used to and quads might not fit with them installed either.

If you do choose to install them make sure they are easily removable.

Jockey wheel

Fitment of a jockey wheel to a large trailer is a must for usability. The bigger the wheel the easier it is to move on rough terrain. What I wouldn’t recommend is a pneumatic tyre (inflatable) guaranteed it’s flat every time you go to use it.

Trailer accessories and finish recommendation

To keep weight down, cost and ease of repair I would get my trailer painted. After that I would get these accessories:

Stone protection on trailer plus a full row of truck mudflaps on vehicle
2 spare wheels mounted under the trailer with Hilux style spare wheel mounts
facility to hold 10 fuel/water containers across the draw-bar
2 recovery points on the rear of the chassis for a recovery bridle
2 under tray tool boxes for general storage
large diameter regular jockey wheel

Perfect Hunting Trailer Deck Material, Length and Width

How big and what material should you make the trailer deck from?

The chassis of the trailer is going to need to be made from steel, I don’t think this is avoid able. Aluminum will fatigue and crack on corrugations, that’s way no camper trailers have aluminum chassis’. So we are only looking at trailer deck.

Deck material

Deck material and sides affects the trailer in 2 ways; weight and usability.

If you choose to make the trailer deck from steel it’s going to more resistant to abuse but weigh more. But make the trailer deck from aluminum it wont handle abuse but will be much lighter. A wooden deck will not last in the whether and can be very slippery.

As I mentioned in the GVM article aluminum is strong enough for general use, treated with care it wont let you down If you use ute tray back style aluminum flooring you could save considerable weight, with fantastic usability.

Length of the trailer deck

Don’t make the trailer to long, it’s too easy to go “Well I’m building it, let’s go BIG”. Just make it long enough for your needs, to keep the weight down and maneuverability.

What are you going to tow? Remember you still need to be mindful of your GCM.

The quad is 1,200mm wide and a side by side is about 2,500mm (not including tray over hang). If I wanted to fit 2 quads and a side by side this should fit on 4,900mm. This is getting very long though and I wouldn’t consider going much past this.

If you just want 3 quads on, you only need 3,600mm etc. I think for 3 quads would be the smallest I would consider building.

Be mindful of your axle placement, there are lots of camper trailers out there with single axles placed to far back and this puts massive draw bar weight on your vehicle. Draw bar weight is included in your GVM and excessive weight ruins the ride handling. At www.trailersauce.co.nz they recommend 75mm rear of centre.

Width of the trailer deck

The width of the trailer should be similar to you tray somewhere between 1,800 – 2,000mm – as the wheel track really determines the width.

Hunting vehicle and trailer weight AKA GCM

photo of hilux with quad on back and towing single axle trailer

What is your hunting vehicle and trailer weight?

Previously we spoke about your hunting vehicle weight and determined that the best option was to use a trailer to keep you legal. This should help you avoid overloading your hunting vehicle. So lets look at why this is the best option.

What is GCM?

GCM is Gross Combined Mass, that is the maximum weight the vehicle manufacturer has allowed. That is the total weight of the vehicle, trailer and all the contents. This is one of the reasons the Ford Ranger is a favourite amongst caravaners, because of it high GCM.

Hunting vehicle and trailer weight example

If we use our example of the 2013 Toyota Hilux dual cab manual turbo diesel from the hunting vehicle weight article, it has a GCM of 5,210kg (sourced from redbook.com.au).

Previously the maximum weight we could carry was 990kg (including occupants and everything) with out a trailer.

Lets say the average dual axle steel trailer with brakes weighs 650kg (guestimate based on approximate weights sourced from www.trailersauce.co.nz). We will not talk about the trailer GVM (maximum total trailer weight) to keep it simple.

GCM Table	weight	quantity	Sub-total
Hilux	1720	1	1,720
Tray	250	1	250
Side steps	15	2	30
Bullbar	75	1	75
towbar	40	1	40
Under tray tool box	7	2	14
winch	27	1	27
recovery gear	20	1	20
Water	20	1	20
Long range tank	40	1	40
Air compressor	10	1	10
Bash plates	30	1	30
spotties	2	2	4
Occupants	85	2	170
Dog cage	40	1	40
Dogs	40	2	80
Fridge	40	1	40
Firearms	5	4	20
Ammo	50	1	50
Quads	300	1	300
Unleaded	15	2	30
Cooking gear	40	1	40
Sleeping gear	30	1	30
		Total	3,080
Hilux GCM			5,210
Trailer			650
		Balance	1,480

So straight away you can see you have an extra 1,480kg of carrying capacity, simply by towing a 650kg trailer.

Lets put that in perspective. Let’s add 2 more occupants and 2 more quads and see how much spare weight we have in a hunting vehicle and trailer weight combo.

GCM Table 2	weight	quantity	Sub-total
Hilux GCM			5,210
Hilux and load			3,080
Trailer			650
Occupants	85	2	170
Quads	300	2	600
		Balance	710kg

Instead of being over weight by 370kg like in the Hunting vehicle weight GVM article with just a hunting ute, we now have 2 more hunters and 2 more quads and still room for 710kg of heaps of other hunting gear!

As you can see the advantages of taking a trailer on a hunting trip is significant. In the past I’ve personally towed a boat just to move the weight load off the tray (we didn’t even think about actually using the boat).

The boys from www.hogsdogsquads.com.au have a custom built trailer purely for the purpose of hauling quads for massive hunts up in the Cape. Check out their YouTube video below for a quick look at the setup they have created:

Towing a hunting trailer

For those of you who have never had a trailer before and are concerned about the difficulties of it don’t be. Normal driving with a trailer is very easy. There is only one thing to remember: that you have a trailer on when changing lanes/overtaking.

If your trailer is wider than the tow vehicle, just check the mirrors to make your the wheels are in you lane or not in the gutter. I find it help full to find a spot on the bull-bar to keep aligned to the centre stripe on the road.

Reversing a trailer is something that takes practice. Just take your time and get someone to make sure you don’t hit anything including the trailer on the tray of the ute. Once you learn how the mechanics of reversing a trailer works it’s a breeze.

Dual axle trailers are actually much easier to reverse than single axle trailers, mostly because of the increased length. So don’t be scared to go big straight away.

Conclusion

Get your self a hunting vehicle and trailer setup, stay legal, stay safe, take more mod cons and really be able to enjoy your trip.

But remember shift all the weight to the trailer. The towball weight is part of you GVM. If your not careful you will still be over your GVM but under your GCM and therefore not legal.

Coming soon the best hunting trailer setup.
