I appreciate all the encouragement, guidance, and suggestions. I'll admit that I am becoming concerned about many of you insisting that these repairs must be done by Prevost. The two Prevost centers closest to me are Goodlettsville, TN (245 miles) and Jacksonville, FL (392 miles). My local RV center of choice, Apalachee RV in Auburn, GA has taken care of the bus since I bought it and is factory trained for AquaHot and many other converter side systems. They also have solid hands on experience with Prevost products and have excellent customer testimonials. To the extent that I am unable to make an extended trip to a distant Prevost service facility and am very reluctant to just "drop the bus off" and leave it to be repaired in my absence, my gut tells me to let Apalachee step up and handle the repairs, so I can at least do personal hands-on inspections as the work progresses. What say you? Am I naive? (wait - don't answer that!) I mean - is there any reason why I should not let Apalachee take this on, since I intend to "ride herd" on the process? For what it's worth, Apalachee has an excellent reputation with my insurer, American Modern.
