I have owned five RVs through the years and dealt with a multitude of dealerships. The absolute worst, by far, is Desert Autoplex in Mesa, Arizona. First off: it takes several days and many phone calls to get someone to answer the phone. You get recorded responses such as: "No one is available to take your call" or, "Hold on while I tried to connect you" and then you get disconnected. Then when you do get someone, they are usually quite vague about whatever information you are calling for be it service, sales, or administration.
I bought an RV from them which required some immediate maintenance. I picked it up after they handed me the signoff sheet and I trustingly drove off only to find a day later that some of the work had not been performed.
There are some really nice people there trying to do their job but they seem very shorthanded and very poorly managed. There are many shortcomings, i.e., the telephone service, which could be handled easily if only the owner/manager would take an interest and do something.
Note the BBB has a big REVOKED on its Desert Autoplex site.
