you could also try Sustenpass, but I have heard varying reports as regards quality.
Had nice memories from Mello about 17 years ago when I first went (managed to make friends with a little mouse on the campsite) so may head there anyhow.
I fear Mr Squeek may have passed away by now
ps Bonjoy; are you kitting up your van yourself? I am hoping to make the bed/seat (with help from Andy Long if it can be arranged) but probably buy a couple of units from the guys at Amdro...
