We are looking at a 2009 Dethleffs frotera t5915 next weekend and want to know if anyone has v experience of these? it's a rear lounge which is what we want 3.500kg small garage, low profile,onboard fresh water , excellent excellent payload at 750kg which is great for our fulltiming use. Not much to change from our swift voyager which is too big on a 4002kg, we have to change next year anyway due to Terry being 70,he doesn't want to chance the medical, we haven't found a German quality van with a rear lounge before except older hymers. I can't find feedback, manuals or specs on the van even on the official dethleffs webpage . Any feedback good or bad on this please before we part with hard earned , never to be replaced cash?
