I just thought I would let everyone know of the great service I received at WW Williams Truck repair in Tucson. I obtained the Sanden AC compressor in advance and made an appointment to have it replaced , the AC lines checked and pressurized, and a new Receiver Dryer installed. They estimated between 3 and 5 hours labour and completed the work in about 4 hours which included cutting off and replacing a seized connector on one of the coolant lines. I thought it was all very fair and their shop is extremely clean and modern. The staff were very friendly and accommodating. They even have hook ups on site and offered to let us spend the night. The previous estimate I had received was from the largest RV dealer in the area and they suggested 10 hours minimum at $149.00 per hour. Just ridiculous so it does pay to shop around.
Kudos to Adam and Desaray, and of course the RV tech at WW Williams. They do all service including AquaHot, engine/transmission repairs, alignments, etc.
