Bottom Line: These are some really nice people and they treated us well; however, they do not understand dash AC systems or dash wiring in general. They also don't pay a lot of attention to detail. Now the long version: Returned a second time for repair that couldn't be completed on first visit back in March. Dash wiring harness for heat and AC controls had shorted, smoked, burned, melted, etc. They ordered new harness, found additional damage, ordered additional harness, tested, tried things out, burned out 2nd harness and had to repair it. Obtained schematics from the manufacturer. I finally studied schematic myself (old electronic tech) and told them what the problem was. Fan relay control side shorted to positive, when ground is applied by pressure switch wiring harness burns up. They couldn't find the relay (and we'd already been there a week) so I asked them to rig up a quick work-around with a manual switch to control the condenser fan. During the week, they had replaced the compressor. The new one had 2 pulleys, and they ran the belt on the wrong one, so the belt failed about 200 miles up the road and had to be replaced. Again, very nice people, and Barry treated us OK on the bill considering they failed to fix the root cause of the problem. I hesitated to write this up until now (a couple months later) because I wanted to get the whole thing fixed and know what I was talking about before being critical of them. So don't avoid them based on this review except for Chassis Wiring issues and Dash AC. I've heard from other customers they are really good with RV appliances, brakes, generators, etc.
