    Gary, the owner is unreliable and shady. He charged us for work that never got done along with…read moreovercharging for items he was supposed to have done. We are both retired and on social security so appare we were an easy mark. We paid up front because he said he needed us to so he could order parts he never ordered. A second appraisal revealed that many of the repairs did not get done and revealed two to five times the cost of what most RV Mechanics would charge. We disputed the charges with PayPal and won allowing us to recover some of our loss. All in, he charged over $10,000 and we recovered about $3,300. Stay away from this guy!!

    I called him out to help with my truck not starting. He charged me $180 just to come out. After…read morelooking at the engine for maybe 10 min he said it's 100% the ignition coil and charged me another $40 for the part and $75 for the installation. Only as soon as he got the part he said it actually wasn't the coil and he needed to test more things. Stood around chatting for a couple hours with about 15 non consecutive minutes of work put into the engine he said he needed to take his wife home and never came back. He didn't do anything but unplug the coil and leave with my $295! Oh and get this, he spent a good portion of the time just virtue signaling, telling me how he doesn't understand why people don't respect each other blah blah blah then steals my money! Keep in mind I do not live in Arizona, I'm just driving through and I'm poor af. So now I had to find another mechanic and pay to have it towed to the shop because I can't trust these sleazy "mobile mechanics"
