Camper construction materials
Hi all,
A little while ago I built a slide-on type camper to go on the back of my 300Tdi 130 trayback. I was very happy with it until recently I weighed the plot ready to tour - 3.1 tons!
I know this is within the GVM of the 130, but it is still too heavy for my liking.
Some things I can't lighten, like 2 spares, 140 litres of fuel, d-gas system, winch, 100 litres of water, etc etc, and the only thing I can really lighten is the cabin itself.
I made this one with an RHS steel frame covered with marine ply. It weighs in at 300 kgs, and this is probably the only area in which I can save weight.
Dois anyone know of any lightweight cladding materials suitable for the job? I have considered aluminium outside, with 25mm of insulation and 3 mill ply inside, but the weight saving is only small. What I would really like is some composite or sandwhich material that is strong enough to support an aluminium frame, not more than 25mm thick and weighing as little as possible.
Thanks for any suggestions,
Cheers,
Paul

Hi Paul,
There are composite products available for caravans and the like. They have a hard skin, and a layer of insulation, along with I think a layer of thin plywood.
This is layered together and makes a fairly rigid and light material. It is available in a number of different thicknesses.
I cant remember the names off the top of my head, but will have a bit of a scan about on the net.
I had a few dealings with this stuff as I designed a camper body for the rear of a unimog a couple of years ago.

Paul, try doing a search for "Nida-Core" or "Core-Cell".
These are honeycomb composite materials that are very strong but very light. Used a lot in boat building.
If you take a look at this site, a bloke has made his own camper from this material:
The Super Camper
Scroll down to the bottom of the page (it's pretty long - you'll need broadband to load all the pictures) and you can see how he built it from scratch.

Wow, Ho Hars, what a ripper job! Thanks very much for pointing me to the link - very inspiring. I will now hop on the net and look for alumiclad. It looks the part, too, at least it does in your camper.
Did you feel a need to do anything to the suspension? Mine still steers beautifully, but it feels a bit top-heavy and I live in constant fear of tipping it over......
I made mine with a steel frame clad with marine ply. For the next one, I hope to learn to weld aluminium and save a lot of weight that way. This cladding should help too.
Cheers and thanks again,
Paul

we put a heavier sway bar or anti roll bar ....25mm for memory the biggest recommend....and new bilstein shocks in the rear.... it has sagged a bit from our 6 week trip we may put air bags in the rear yet.. otherwise it does not roll too badly and we did a bit of 4wding while away....Plenty h/way..Tanami track...Gibb River rd...Nathan River rd...Savannah way etc fully loaded with 140lts deisel, 100 lts water, gas bottles x 2, food etc and yes 3ton but that is why we have a 130........to carry that weight...

Thanks for the info. I will need to look at something similar.
You have done so well for weight. Mine, a single cab 130, with similar water and fuel weighs in at 3.2 tons - and I don't have a cab-over, just a 3 metre by 2 metre pop-top box. I really will need to learn how to deal with aluminium!
Cheers,
Paul
