This is a much harder question than it was some years back.
I have never gone to CW for Body work.. and will not. Have had them mess up some other work, 100% of the time. and that's why
Today you have body shops and you have BODY SHOPS
Many modern shops just replace fenders.. they don't actually FIX just replace. imagine the cost to replace the entire passengar side of your RV.... OUCH
But I had an older body may (over 50 years in the business) and he was fantastic, If he could not find the part he'd make it.
I also had one repair done by a much younger body man. I saw the work he did on cars (I was having major other work done at that shop) (Xtreme Auto. Townsend GA) and saw the job this kid did. So I had him do some needed body work.. And I was not in the least dissappointed. But he is a "Fix" not a "Replace" type body man. he did a good and proper repair. Just like the old man I used to use (He is no longer in business by the way. Retired).
