I was not aware there was a max towing speed.
I pulled my camper 2004 TM 3023 from Indiana to south Kansas at speeds of 70 +.
Last part of the trip I was on Turnpike .... Speed limit 75. Probably hit 80 mph a few times
Trailer towed beautifully .... Hardly knew it was behind my 96 Silverado 3/4 ton
Checked tires and hubs. About an hour into the trip and a couple times after... They were not hot.
Trailer was empty.... Just bought it.... And was bringing it back home.
