Thread: Building an Off-Road trailer

Anyone built a trailer with independent off-road suspension? Sort of thing you see under Aussie campers etc.

And does anyone in NZ build this sort of thing?
I'm wanting single not tandem, without the axle right thru, to carry around 2 tonne?

Try Central Custom Engineering in Alexandra. Aiden designed & built his own for his offroad caravan. They have a full CAD design service & waterjet cutter.

If your not going full hardcore with it would durotorques do just as well?

Avoid them if possible for off road type applications. They have a very firm action.

Second that, if you start pounding duratorques with a load on they start doing all sorts of nasty like cracking the ends of the axle beam where the rubbers are inserted into the axle... And they take a sag if the load is on them consistently - they prefer to be left fully unloaded and only loaded for a short time then unloaded again.

2T load will be pushing it on a single axle setup like that. It will be serious money just for the suspension/hub/brake setup.

Yeah I'd like to stay single if I can. And the 2 tonne is not essential, but the Aussie's like Cruisemaster do them like that.
And you're right about the cost, but I'd rather spend up front & have something that won't give as much trouble.

Anyone of you engineering/fabrication types had much to do with ally trailers? I've seen some big boats, around 7-8mtr on ally trailers, what's the thinking on how well they last? And it's life includes getting dragged around off road by a Unimog.
It's not going to be a winch truck, but we won't be babying it either.

The only ally box trailers I have had anything to do with cracked in all the big stress locations pretty quickly. And that's not even off road. Could have been poor design. Off road will stress a trailer quite a lot more than a trailer staying on tar seal.

Thanks XR, kind of what I was thinking, I'm taking a look at the Cruisemaster independent suspension next week, there's some here that my Camper builder has.

It's supposed to be pretty good. Figure if it looks good I'll try that, with coils, not the airbag version.

Here's a pic you might like, given your forum handle!
