This is a very simple update that I should have done a long time ago. I don’t know if this setup was unique to our coach or if its common.
The plastic material that forms the AC cover / shroud tends to harden over time. They generally last 5 years, at which point they should probably be replaced, but who really tracks that.
Time for some tow bar maintenance! Our Blue Ox Aventa LX has served us well, but was getting a bit stiff to move ball-in-socket and the arms, plus there were some creaks, squeaks and groans (Oh My) when any of them were moved.
