65mph is max speed rating on ST tires. We tow our 42' 5er at 60 to 65 mph if speed limit allows for it. But we go 60 mostly.
He's just plumb crazy towing 80 mph one day you come across him in a ditch with all his rig messed up. He's also endangering everyone on the road. I tow with a Ram 3500 DRW weighing 9000# and my 42' 5er weighing 17500# loaded so that's 26,500#s and at that kind of weigh would plow right the anything on the road except an 18 wheeler.
Be safe on the road and live to camp another day!!!
