We have a 2009 MS 38tksb3 and have the new Trail-Air Tri Glide. We had a problem with chucking. It was so bad we thought we would have to wear neck braces. Went back to dealer and they worked all day changing settings on hitch, trailer, even changing hitch, changing trucks and then when backing the unit back into the bay we noticed the front to back movement in the truck hitch of about 1/2". We have the Husky hitch and the main bolt holding the hitch to the hitch stand was loose. We tighted the nut on the bolt and solved the problem. Check to see if you have any forward to back play in the hitch and check for wear in the hitch jaws or on the king pin. If slider hitch check for wear in the holes on the slider rail.
