I would think it's time to go to a big RV show, and bring the camera and the family.
What you go with might depend on how long you plan to keep the unit. The bunk or dinette sleeper that would work for your kids now might become cramped a few years down the road.
Even if you go used, the RV show is a good way to see all kinds of floor plans in one place, and firm up what might best meet your needs.
