I owe these folks an updated review. About 10 days before my scheduled departure from Mesa I called Arizona RV Repair and stressed that the clock was running out. They promised that they would be here to do the repairs. They showed up on time and stuck with it for most of three days and didn't quit until the job was finished. The slideout motor replacement turned out to be a bigger job than I thought and it took two days of hard work to get the old motor out.
Once they were on the job, they did really good, thorough professional work. So I guess that my only complaint is that it took a long time to get scheduled but that really didn't cause any problems other than my stress as long as the work got done before my departure date, which it did. So I'm up voting Arizona RV to 4 stars based on the quality of the work.
