Somewhere in your travels it appears you have 'hammered' a bump/pothole at highway. Look at the torn fabric above the tire. While that fabric contact is not unusual, it happened on our 343RL but nowhere near as bad as what yours shows. If your HC has 5200 pound suspension as ours had, it really needs to be upgraded with 6000# springs. I also added a 1" spacer and 6000# outer wheel bearings (along with disc brakes). While not a cure-all, it will help with spring compression and rebound and possibly a whipping motion that may have caused that damage. I know that the heavier springs and added spacer corrected a nasty wallow over bridge approaches and departures


Then there is the chance that yo dragged that rear frame hard such as going into a poorly designed gas station or similar driveway as I have with ours. You wont even know that you did it until you notice that the rear bumper plug is gone
