Something else to keep in mind. When it says Sleeps 6 they usually mean 2 adults, maybe 4 if 1 couple doesn't mind sleeping on twin bed. The other 4 are kid sizes sleeping accommodations.

We looked at a 22' that "slept 4" there wasn't enough room for 2 adults comfortably and what ever luggage, camping gear, etc one wanted to take. The 26' "Sleeps 6" yeah us and the 2 pups.

Storage, Storage, Storage. The interior may be what you and the spouse "always wanted". It's how much storage room is there for that trip.

Last item is ...Where is the bathroom in relationship to eating and sleeping area. Rarely will you want to make use of it when there's a few people with you. Just sayin.
