I have similar ideas - and have got as far as acquiring a lwb tub to start from. My intention is to make it sufficiently light to be unbraked. The chassis will be made from scratch using rhs steel. Undecided whether to use new trailer springs or front Series springs minus a couple of leaves.

The main feature I plan is to use the rear end of another tub to make it double ended with a tailgate both ends - very useful for carrying long loads.

Wheels will certainly be Landrover, probably swb for lightness, and at the moment I am thinking of a tubular axle with a Series stub axle bolted on each end, although I have seen suggestions that solid one piece axles are mandated, so this may need modification.
