Anyone over see this? Towing my 5th wheel heard a loud bang, found this buckling in towards the hitch. I did have two folding tables strapped to the passenger side parallel to the cab. A 5 gal propane bottle and a large Bluetooth speaker forward left side of bed. No damage to anything other than the bed. Propane bottle never moved but my speaker did move on me, again no damage to the speaker. I had two jack straps crossed from one side of the bed to the other holding the tables in place.
