The way I see it, they messed up and they had it fixed..... at the dealer, like you asked them to. I'm sure the RV dealer's techs could have easily changed that line with ZERO problems. Other posters are correct, most dealerships do not touch aftermarket at all, they sub it out every time and you pay the markup. I have an aftermarket shop with 3 guys that do nothing but pick up vehicles from the dealer for all kinds of things. People make mistakes and if at my shop I would have fixed it myself and you could have taken it to the dealer if you wanted it double checked. It was a very simple fix...
