"Been doing my maintenance on our motorhomes for 10+ yrs. Always do great work."

"Rex is awesome!!! I needed a safety inspection on my motor home and they were fully booked. Rex told me to come in before they opened and he did it then for me! He was very thorough and great to work with! Best costumer service I’ve had from a diesel shop anywhere! He is a hero and saved our vacation!"

"Dropped my truck off 9 months ago with a VATS(vehicle anti theft System) code. The truck ran fine when I brought it home and had a dead battery in the morning. Jumped it and it never started again. Took it to the dealer and they said my 40000 mile injectors were bad. Took it to SWD and was told I had bent push tubes. We decided to put a junk yard motor in it and I was quoted $4800 installed. I said sure. Do it. The next day they asked if they could repair the motor. I said sure, as long as it's not over $4800. For months I would call to see what was up and got a different story every time. At one point they asked if they could have more money because there were other problems. I ok'ed $7800, for the repair of a $9000 truck. More stories (and lies). Heads were warped. Waiting on the machine shop. It's back together and It doesn't run right. It needs injectors. It needs a cp3 pump. Now it won't stsrt.they admitted they ran it on ether. They said they took it to the dealership because it wouldn't run. Dealership told them it was a computer issue, which I did believe based on the codes I pulled from day one. Months and months went on. I called every two weeks They said the dealer had it for 2 months. Finally, I asked if I could just have the truck back the way it was. If it was at the dealer and wouldn't run, it would at least be able to be sold as a non running truck. I picked the truck up on Wednesday Dec 23rd after dropping it off on Mar 21st. They were very helpfull loading it up. I pulled the truck back home to Vegas and pop the hood to take a look. I was told that the intake parts were in a box in the bed, but what I saw was unbelievable. They decided they wanted their parts, so they destroyed the engine bay pulling them out. It looks like the truck was the victim of a pick-apart lot. They threw the fuel system inside the cab, which now has diesel everywhere. They tore up the radiator, cut off fuel lines an inch from the clamp, wires were ripped out, every computer was removed, firewall insulation ripped up, rocker arms and push rods thrown in a box and a huge bag of bolts. They said nothing about removing parts. I thought they would charge me for the parts they installed. I was willing to pay for the parts. I understand this was a bad deal for them, but it was their decision to try and repair engine as opposed to replacing it. I just wanted to replace the motor and they wanted to make some extra money by repairing it, which they clearly were not capable of doing. I only hope someone else will be spared the experience I've just had with Southwest Diesel Service."

"Dealing with James at South West Diesel Serv has been a pleasure. This is my second time dealing with them and it was as good an experience as the first. From minor repairs to major, I fully trust them to handle it. They have definitely earned my business for life."

"Just had my car finished by James and I must say it was the best service I have ever had. I was filled with confidence when I drove my car for the first time. After all the service it had It was running so much better than when I first got it used. He explained to me what needed to be done, in a way I could understand, and was right on the money on his diagnosis. I could not be happier and will definitely take my services back to him on all my autos and RV. I highly recommend if you need service, James makes the difference"
