If you choose a F250, you want the camper package and 18" wheel options. This gives you a F350 with F250 badges plus front and rear stabilizer bars. Buying a F350 with camper package just gives you the additional rear stabilizer bar because it already has the rest.
If you want the smallest toy hauler that can haul a UTV, look for an open floor plan with forward bath or kitchen. You will need to unload the toy to sleep in it, so that is downside to something so compact. Why not haul the UTV in the enclosed trailer and have the family in the truck camper instead of owning two RV's?
