Structural differences between PVC & coachbuilt MHs

[DandJ]

Have you considered simply buying an refridgerated ex delivery van... a few people have, and done decent jobs of kitting them out...

I watched their conversion with keen interest. He and she (or the editing), make it look very easy.

Unfortunately, it's just not big enough for my needs. I am looking into the adaptation of one, to have a longer chassis because they seem to be cheaper than what's on AutoTrader.

The specification of the box in my build is similar but, possibly, with newer components. Sandwiched between GRP & probably uPVC (thickness to be determined), will be 50mm of PIR foam with a 0.01 thermal conductivity value. That's the walls.

The floor will have a floor-spec variation, which stands up better to compression and the roof will be of a roof-spec, non-sagging version. Possibly also, alloy joists within the roof in case some maintenance operative (or me when not thinking), may get on it, instead of using scaffolding.

Or you could look at it another way, you put a caravan on top of the van chassis and keep the cab at the front.
