Let me start by saying hello. Just purchase a 21FSB for wife and I to travel local to lakes and mountains in NC. Here is my question, The first time I backed up to park and store the camper I removed the sway bar but left the chains on the leveler in tack. As the traveler turned at an angle I hear a loud pop and found the bracket mounted to trailer with the chain attached slid 5 -6 inches forward scratching the paint off the trailer. The dealer said that should not have happen and normally you do not have to loosen the chains but to prevent this from happening again go ahead and loosen the chains next time. So I am curious how many loosen the chains before backing up in camp sites when having to turn at any given angle. Thanks for the feedback.
