I think your question is about a toy hauler not the DP you mentioned. I have no idea what my 32ft Pace tri axel trailer with a door car, atv, generator, etc weighs but I have towed it over 100,000mi behind my 40ft Winnebago DP with a factory hitch and never had any sign of a problem. I check everything closely and often. What I find on this site is often more what you can't do rather than what you can do by experts that have never done it...But I see 7000+lb trailers all over the race tracks many being towed by 1/2 ton pickups and class C motorhomes which I doubt have a class V hitch..Just my thoughts.
