The Keystone premier 33blpr is very long, but is within weight limitations of a half ton truck. It has bunks, and a rear living area.
It is however expensive. For the price of one, you probably could sell your half ton, buy a used 3/4 ton, and buy a Coachman Catalina 313rls. It has the same floor plan, and is probably close to $10k cheaper. Technically it is within weight of a properly equipped half ton, but is probably more than most half tons can tow comfortably.
One other option is to find a TT with a free standing dinette. Remove the dinette and put in recliners. Use a folding table and chairs when needed.
