With my rzr 800, full water, all bedding, fridge loaded etc I weighed in at 11900!! It's the limit for my truck! If I stay at 65-69 it pulls great but interstate speed it's white knuckle driving for sure and now I just take back roads when possible! When I was dealing in camper they said they have a lot of guys pulling with half tons, I was in question but trusted them! I wouldn't recommend it all.
