Hi Guys, Have been reading the thread with great interest, great job. I couldn't imagine being able to do it myself, very impressive.
I had a LWB Ducato done by a camper van converter guy. I bought a H2L3 with 28k on the clock in 2010. I wanted the garage big enough for bikes at the back, so we had a permanent double bed installed above the bike sized garage, you can get 3 bikes on with the front wheels off. The problem is the van starts to narrow the higher you go and it's about 10cms too narrow to stretch out in. But it's fine for the Mrs and our son. If I did it again I wouldn't have had the bed mounted so high, as it doesn't need to be, with the front wheels off bikes they are quite low and more space in the bed area would be useful.
It's got two single seats at the front on swivels, I bought a Ducato single seat off Ebay. And then two belted seats in the back on a raised floor. Shower room, toilet, two burner stove and fridge.
The front section converts into a big double. I've had a few problems with condensation in it, but a rotating van vent thing made that better.
Also had a leak from the van roof which was a bugger to find and wrecked some of the interior.
Heating is from Gaslo on LPG which is excellent and runs for ages.
Best thing is it's quite stealth like, so you can sleep anywhere and not get noticed.
