It'll be a progressive thing.. Initially we're just installing tie down points for the buggy, a workbench with vice, tool box(s) some wall storage, 12v power points and 12v lighting in side the pantech and some 12v spotlights outside it.
Phase 2 involves installing a generator and fitting the 240v compressor I already have. May consider a shower in one corner. We discussed fitting 6 bunk beds, but it's more hassle than it's worth.. Just roll out a foam matress on the floor of the truck and we're good to go.
Won't be having AC/heating in the pantech either, although I looked at some refridgerated units which would make summer events rather cool
the BBQ isn't something I'd thought of, but it's a great idea! might look into how easy it would be to put something on rails.
