Camping World would not be my first choice of somewhere to have body work completed. Beyond that most RV dealers would not be my first choice. Only because my experience suggests that body repair is a small part of their overall repair business, thus they are not the best choice.
In some parts of the country finding capable shops with a building large enough to accommodate an RV is problematic.
I would seek out a commercial truck/bus body shop and expect them to be more than capable to repair an RV. Previous posters suggested seeking suggestions from your insurance agent, and I would go even further and suggest asking the company's adjuster for suggestions. Usually the adjuster works for numerous insurers and is more likely to give good advice. You may get several suggestions as they deal with most shops in a fairly large area today. Once you have a few suggestions it is simple to check out some of their work from previous customers if you feel the need. Sometimes just looking at a shop's facility is enough to make you feel comfortable with their potential for satisfactory work.
Whatever you decide, best wishes for a positive outcome.
