          Table squeaking; slide out binding; engine overheating light activated when coach was not hot. Poor - I had to take the coach back twice; the work was double charged (once under warranty and then once to me; it took several months to get an appointment and several weeks to get the coach back; much too small of a storage lot; Tim (owner) angry when I returned the coach; I received my bill in November for work done in July.

          We have used M & M for all warranty work and basic service. Cook top recall, slide adjustments, rattle in entry door, awning adjustment, oil change, oil/fuel filters, lube, generator service, Powergear jack controller board. Excellent. Tim the owner and Jesse the tech solved all my issues to satisfaction. We use M & M exclusively.

          Very complex prob with gages shutting down intermittently on 2005 Journey. Kept coach for 31 days but kept advised. Worked directly with Freightliner and finally fixed prob after disassembling much of the underside of coach to check wiring. They fixed the problem the 3 other Freightliner shops in the LA area could not. Excellent. Jesse, in shop, and Tim, the owner, both worked with us closely. Will use this shop exclusively in the future.

          Star Extended Warranty work on 1997 Monaco Windsor Dealer kept motorhome for 3 days without a response, than asked for over $400 just to evaluate the problems, before they would call the insurance company to see if the problem was covered. My A/C pump had frozen. You could open the hatch and try to spin it and see it was frozen. AFTER I showed this to them, the wanted $95 to check it out! I felt it was usury.

          Repair leak in refrigerator, new shocks, change oil and service generator. Great job.Ice maker works great. New shocks unit drives great. Been taking my unit here although its a drive from Palm Desert. Great work and the shop foreman Jesse has great information. I would not take my coach any where else.

          Suspension Air pressure loss - was losing 50% pressure overnight. They improved the situation: still some pressure loss, but now is "acceptable" according to Freightliner. Adjusted ride height, coolant level. Work done was good. However, after I specified "Warranty Work only", was still charged $180 without prior approval, I told me to get Winnebago or Freightliner to reimburse me. Freightliner did reimburse me, but didn't like having to go that route.

          Changed batteries and did some wheel bearing work and lube service. Charged me for 12 volt batteries but I asked for 4 six volt (had to bring it back). Also did not replace fuel filter when doing engine/lube service and found PAC brake disconnected after their work.

          I had my windshield replaced on my Coach Coach When I came home it was cracked on both sides. They said it was my RV moving and my RV was made wrong. I had another one put in and it's fine. The company that put it in noticed the caulking was missing in places around the glass and that is why it probably cracked; it didn't hold it correctly. They also told me that it should have sat longer then it did to cure properly. The owner of M&M didn't care at all. Had a bad attitude. No customer service.

          Miscellaneous. warranty work I found the entire staff including Tim the owner to be unfriendly and uncaring. I had to return coach for more than one re-adjustment. They estimated my portion of the bill to be $200, but that amount increased to over $400 when I picked up the coach. This was done without my approval. I was treated terribly when I questioned their practices.

          New Toilet. Fixed short causing the dash air to close and blow fuses. Service radiator and engine. Install air hose from the air compressor. Everything was done to my satisfaction. This is a great repair shop with a good owner and shop foreman.

          Replace entry door handle. Order replacement window. Entry door handle was installed without issue. A simple repair that took less than 30 min. What rubbed me the wrong way was they overcharged me for a replacement window that had fogged. I had already spoke to my coach manufacturer and obtained a price for the window. I had been in contact with Dave to schedule an appointment and he suggested they order the parts to simplify the process since they were going to do the work. We exchanged emails and I included the part/window price I was quoted. I even provided the name and number of my contact at the manufacturer to make things easier for him. Needless to say, I was not happy when the price of the window was $50 more than agreed. Apparently, I was charged that amount for them to make a phone call to the manufacturer. Tim, owner, could care less about a satisfied customer and would not stand behind his employees word. To make matters worse, Dave and another employee, Jesse, thought the situation was funny and were joking about it in the parking lot when I walked out to get my coach. How unprofessional can you get? Before leaving, I asked where the new window was. Nobody knew where it had been placed. I found it tossed unsecured in one of my storage bays. Needless to say, it would not have been in one piece by the time I arrived home. I can only imagine how they take advantage of the paying customer on labor. If you choose to have work done here, get everything in writing BEFORE the work is completed or expect a surprise at the time you checkout. Better yet, take your service needs to J&L RV repair and be treated fairly like a valued customer.
