Porpoising
I have a 2013 Ext Cab Chevy Diesel 2500HD and a 2014 Cougar 28SGS with Resse Hitch that I just brought home this weekend. The truck on both cement and asphalt is porpoising to the point it was making...

Do you have a slide bar hitch if so may be your problem. Weight should not cause chucking but a loose hitch or parts will. I went to a lock jaw hitch and no chucking.
