If you are in a CG I would go up to the office and ask who they use for mobile repair.
Just saying. I found the RV mobile repair in Florida VERY 'inexpensive'. I swear sometimes when I get the bill I think I wouldn't even pick up a hammer for that low of a price to fix something. :W
They get in and get'r done and they have all the supplies and parts they need right on the truck while you sit back and have a cold one.
I full time and I use RV mobile repair for EVERYTHING on my RV.
Good luck, hope you have cold air blasting into your RV soon!
