MM, that's where you could use a set of load leveler bars like you use when your hauling a travel trailer. I could haul up to a 35 footer with a 3/4 ton truck and my load levelers would pull the tongue up level, so you weren't nose light and a$$ heavy. You can probably buy a used set from a camper supply store.
Save a lot of excess wear on the rearend(of the truck).
