Is there a 'I wouldn't buy a ? Motorhome' - and why?

My last Beaver contained an Aquahot which was a bucket of parts and repairing and reassembling it was an education. While I liked it there were things like having to refill the fuel tanks every eight weeks that I'm not sold on. Hot water space heating is nice and unlimited hot water is good, too, but the effort and maintenance means I'm moving to electric powered heat pumps both home and on the road. It's the future!
