Very happy with our Heartland Elkridge E22 5'r. Lots of storage and a good size bathroom with corner shower enclosure. Wardrobe space is only thing that it could use more of.

If you get one with the rear deck that slides out you can haul bicycles or generator or whatever.
On edit: Whichever 5th Wheel you end up with, spend $500 and get a memory foam mattress for the bed. Best investment/addition we made to our rig.
