We bought a new Coachman 460/2 last year, for the two of us. We considered a bigger van with fixed bed, but the lounge area of the 2 berth converts into a super king sized bed, whereas in 4 berth vans with fixed beds the lounge area is usually smaller and at 6'4" tall I found the fixed bed in a friend's 4 berth ocaravan that we borrowed was too small. It only takes about 5 mins to convert the lounge to a bed and vice-versa. Shower room in the Coachman is very big, the shower in particular is a nice size. You will need a tow car which is up to the job of towing the size of van you choose, and if you use grass pitches 4 wheel drive can come in handy.
