Thats why I do all repairs that I can do myself! I know the stuff I work on is really done, and correct.
I don't like leaving my coach anywhere for 2-3 weeks for a few small repairs. Last time I did that was for warranty repair of frig, slideout not working right, and jack issues.
Well, they diagnosed frig(needed new temp sensor box), said slide was fine, and jack leaking(cant fix(obsolete system)then charged me $179.
Got home and they called me, we never put the new temp sensor box in coach frig.....had to come to house to fix (took them 9 days to come do it...)
