It's not limited to Camping World, or even RV repairs. Sloppy work abounds all over. I needed to repair a very small leak in the trans line leading to the auxiliary cooler I had installed years ago. This required pulling the front bumper fascia.
The last time the bumper was pulled was by the dealer who replaced the AC condenser. I noticed they didn't reinstall all of the bolts, they had broken a clip holding on the grille, they didn't tighten one of the bolts holding the battery hold down and the other was missing, they left one of the bolts holding the trans cooler and the other was not tightened.....it goes on and on.
Bottom line is, these guys figure out of sight the customer will never know.
