small class C recommendations?

The weight distribution hitch weighed about 50 lb. - very compact weight and hard on the back to get it into the receptacle, as well has up and down to finish the rest of the hitching. We only used the bathroom as a closet and carried water so we didn't have to dump, though our preferences on that may change, especially with preschoolers coming along sometimes! Hoping that we can just get in and go with a small motorhome!

Thanks for all the suggestions! I was hoping there was a true 21 or 22 ft. unit out there somewhere, with the cab over bed for the kids.
