I keep bumping my head in PVCs!
Plus there's not enough room anywhere for any of the things we carry! The winterisation is non-existant, the tanks too small, the washroom to small and not enough berths.
However, for those folk smaller than us, with less kit, close to facilities and who only go out in the warmer months, the convenience of a a more compact PVC is ideal!:thumb:
Mine has a roof height of 6'1". so if you are tall you would bump your head.
Mine is fully winterised. -24C was the lowest temperature I recorded and I was snug. I have a 160Ltr fresh water tank and 120Ltr grey which is bigger than on most coach builts. My washroom has a full size domestic shower tray in it.. How much bigger does it need to be. I only need a 1 berth so that is how I built it. It also has 500AH of batteries, A genny, A twin tub washing machine and everything else I need for living in it fulltime.
If you can't manage it then it says more about your versatility I think than the limitations of the van
