Our kids share the queen sized bunk over the cab. We have a lovely master suite with double bed in the rear, and the four- seat dinette turns into a bed for another adult or a couple of extra kids if needed. I think we reached max capacity when we went to Disney with the two of us, our two kids, my in-laws, plus two big dogs. It worked, and what a trip it was!
By the way, we love to see our RV heading off for adventures with other nice families whenever we can't use it so it is available to rent. Contact us if you are interested in planning a Family Escape of your own.
