Hi, I'm a newbie (only experience so far is a week's hire of a VW Cali in Spain recently). I'm now planning converting a Boxer or Ducato (medium/high roof) and considering double bunk beds across the rear, to avoid having folding beds in the living area. The internal width is max 1860mm so not really wide enough for tallest people but that may not matter. Searching the web for ideas shows that it's been done before (some examples here) and Autocampers even made a commercial model for a while. That's now discontinued, so presumably didn't sell well. I would want a storage space under the lower bunk, min 400mm, for a bike. The top bunk would be only for children and have a smaller headroom. The van will be used mostly by me as a single, with my bike, although my partner will accompany me sometimes. Also it will probably be used by my daughter / boyfriend/ young son(or two?). So, two questions really... 1, can anyone see any potential problems with my bed idea that I haven't thought of? 2, is it crazy of me to attempt a self-build (I'll use pros for fitting windows and some other stuff but I'm OK with house plumbing, electrics etc) when I've so little experience of using a campervan?
