codger, depending on the trailer, "Probably". The rest of the trailer may or may not handle the off road conditions. Sorry I can't be more definative.

Thanks John, I am thinking of upgrading my camper rather than buying another. It's a light 750kg with no brakes, I want to be able to go down the dirt roads easily without damage to the trailer. May need to reinforce the chassie as well. Problem then is increase in weight.

The things that commonly break on trailers in the bush are
leaf springs,
drawbar (bend and snap where they join the body of the trailer from too much weight up forward)
axles
bearings (usually lack of maintenance), but bearing hubs can break too.

Seems like you may have to do a lot of upgrading if you want to take a well loaded trailer over corrugated outback roads. I used to take a trailer out bush before they made offroad ones. It was Treg brand with 1.25T capacity, and had 8-leaf springs, 2.5T axle and chev bearings that were huge. It handled things well. It was built in 1960, and is still going strong.

You can Codger - but wether its practical in your case is hard to tell without any real info.

But its worth considering , that just changing wheels to taller profile tyres, running those at reduced pressure and ensuring the springs are well matched to your load (i.e they are not to stiff like most) , will get you a long way towards your goal.

Good call! Most off road camper trailers are way oversprung.

Hey Codger

I bought a camper trailer designed to be towed behind a 2wd or at least a small 4wd, I needed a camper in a hurry for accommodation for 1 of my guides.

Before I set of on my holiday I am going to change the suspension, axle and draw bar.

Firstly a bigger and stronger draw bar to take a larger box and jerry cans, then the suspension will be 8 leaf eye to eye springs with helper springs and shocks and a 2 tonne axle with larger bearings and a 5 stud hubs.

Just a couple of things to take note of, A 45mm axle is designed to take a Falcon or Holden rim and bearings, so if you put a 4wd rim and tyre on it you are over loading the bearings.

If you put the bigger springs and tyres on the camper you are lifting the trailer higher, this will affect the floor hight of your camper as well.

Hope this helps.

Cheers Steve.

Hi Codger,
No problems if your handy, have the gear, or a mate who does.
Did it to my 6x4 a while back.

Firstly, turn the trailer on its back and weld a 40mm x 40mm x 3mm box section sub frame to the existing chass.
Gusset the spring brackets with 40 x 6mm plate.
Gusset and reinforce the draw bar. Total cost of steel...$75.00.

Most bearing suppliers stock H/D Ubolts and Plates...$24.00 both sides.

Super Cheap stock 500 kg rated leaf springs...$29.00 per side.
They also have Hub and Bearing units for Patrol/Land Cruiser stud patterns complete ready to fit to either a 39mm solid round or 45mm square axles.....$39.00 per side.

A weekends work and $240.00 yer cant go wrong.

Just a quick mention: the springs are slippers and after 5500 very hard kms are as good as the day I fitted them, but many members are of the opinion that fully shackled springs are a better option. I can see why so will be changing them in the near future.

Hope the info is of use to you......Lionel.
