If the RV is aluminum-skinned, the panel can be replaced if it is "holed" or dented beyond the capability of a paintless dent repair service to pop it out.
If the RV is filon or gel-coated fiberglass, a quality boat or Corvette repair facility is often your best bet. If you have a good relationship with your RV dealer, he might be able to recommend someone they have used successfully.
By the way, welcome to iRV2 - we're glad you found us but sorry that it has to be under these circumstances!
