I went to Orlando FL once and would not go back. They overfilled my CAT after explicit instruction and changed all the Transynd at the first service when all they needed to do was replace the filter. But mostly, its because it is a huge place, yo are not allowed anywhere near your RV while it is in the yard, too big and impersonal, never met the tech.
I switched to Ocala FL, same company. Much smaller shop, I liked the manager better and could watch the service tech work on my RV. The tech actually came over and talked to me before he started to make sure we were on the same page and let me know how everything went afterwards.
I would do Gaffney if at all possible.
