The biggest campervan snags I think are having to un-pitch before driving off site to (for example) the off-licence to get more beer, and having to drive a large sluggish and thirsty vehicle (possibly also unstable at speed or in high winds) for the rest of the year - and less internal space than a caravan, usually, which is important for those with GAS (guitar acquisition syndrome). I don't see any big advantage over a caravan and I see several disadvantages. But I hate towing so much (snarl, overtaking all but impossible, and max speed of 60) that I am thinking of scrapping the caravan and going back to tent...
