We've owned our 13'
Scamp Deluxe since 2007 and I'd hate to have camped with our kids in it. When our 4 kids where young we had a Jayco popup, 8 foot box with the beds that pushed out on each end and a gouache that folded into a bed as well as the dinette so we slept 6 people and a small dog very comfortably.
Have you looked into a popup? if not, perhaps you'd be surprised just how well it may fit your family, probably much better than any small hard sided/egg camper like the
Scamp,
