2 Maybe, you want to look for an open floor plan which in the 5er format is a bit of a Unicorn. Are you wanting to put a boat/trailer inside the 5er?
You can start with the Complete List of Toy Haulers
Specifically check out the Genesis Supreme, as I recall the had some 5er Haulers that had optional slide outs, without the slide you'd have an easier time getting stuff inside.
The boat would be towed behind. The space is needed because if I need to give up truck box space, I need to still be able to carry that quad.
