Cajun, if your RV is still under warranty you might want to delay the install of that bike rack. I know for a fact that it will invalidate your warranty as I called and spoke to the warranty person at Rockwood FR.
Here is my OP detailing the welded on bike rack (likely stronger than a bolted on one): Rockwood and rear bike rack
Of course with a hitch that bolts on, I suppose you could remove it if you have any frame, sidewall issues before the factory inspects and repairs. Likely they would see the bolt holes though.
