floorplan that suits you is always the best way to go
we started with a 30 ft fiver 1 slide , then a 30 ft towable 1 slide to a 38 ft triple slide fiver to now a bus with 6 slides
go sit in them, drive them, run off the sales guy, take a few hrs to "live" in it. lay on the bed,
open drawers, open the slides, close em and see what you can get to or not get to,
find what you like and can afford.
