Hybrid expandable or not?

Nothing will be out there under 4klb that sleeps 5 comfortably. Comfort is eye of the beholder sleeping on the horrid couch or dinette. Ours might work but they are hard to find. It weighs 4100lbs wet/ready to camp and has a gvw of 5000lbs. Tent out the front, tent out the side, and rear bunkbeds for kids. Clothes go under front bench in bins, and under side bunk. Towels, and extra food in vertical pantry. Toys and extra bedding go in the bunkbed cubbies at the foot of those beds. 7ft 6 wide, and 1600lbs payload. 3 bed hybrids with out slideout such as the roo 183 or the rest of the 3 bed nonslides will work.
The downsides of 3 bed nonslide: you lose a ton of interior/exterior storage.
