We met some really nice people at Padre Island National Seashore who travel in this really cool Safari Trek from the early 1990s (can't remember the exact year, I think it was 1992, but I know they're pretty hard to come by). It has the most ingenious bed design I've ever seen, a queen size bed retracts up into the ceiling over the front seats when not in use. A four cylinder diesel that gets 15 miles to the gallon ain't to shabby either.
