Hire companies might be the place to go. Britz site, for example, shows several models and layouts. Don't underestimate the value of hiring one for a couple of days to see if such a vehicle will do the job. Many of the conversion companies show lots of layouts on their sites. I bought a Four Motion VW to do my own as the commercial offerings have lots of features I don't want and don't want to pay for.

As well as following up Iza's thoughts above, you might also consider popping into several local caravan parks / shopping centres etc and talking to people in vans similar to the type you're considering, to ask them about the +'s and the -'s of their van's setup
If you consider taking along a $5 bag of chokky frogs as 'bribery' for their time with you, you might get heaps of feedback as well as seeing various floorplans & construction arrangements, all of which will make it easier for a final decision
My van was originally owned by a Tassie gentleman who brought it up to Melbourne to trade it in for something bigger. It has everything except a shower.
There must be more down there, keep looking. Perhaps ask around the Toyota dealerships. Good luck.
THANK YOU everyone! lot's of good advice, we will follow up.
we did hire a van for a week, to see if I froze to death or not!!
was all good, [despite 1 deg c at Cradle], with small fan heater and tons of down bushwalking gear!
just like backpacking [hiking] get dressed before get out of sleeping bag!
the model van was VERY old, tons rental km's , so not a good driving or layout example.
cheers Tas quoll
