  This will be one of at least two reviews for Cummins SA. This review is specifically for Wes, who I believe is a Service Writer at Cummins San Antonio. We have a 2018 45' Entegra motorcoach. We broke down on RR 12 just east of Hwy 290. Clutch, transmission, something... The engine was running fine, but when you hit "D," it sounded like gravel back there. This was at about 4:15 PM on a Friday. I called our roadside assistance (Good Sam), and they wanted to send me to Round Rock. We live at Canyon Lake, so I wanted to go to San Antonio. I called Cummins San Antonio at around 4:30 PM, and they put me on with Wes. I told him we were still searching for a tow and that it would be at least 8–9 PM before we could get there. Wes said, "No problem, call me when you get close, and I'll open the gates." As time went on, sitting on the side of RR 12, tow drivers were just canceling and saying they wouldn't or couldn't do it. I called an old friend of mine who has worked in the diesel truck space for a LONG time. He told me to call a friend of his, Jeff Chapman with Chapman Towing. (This will be another review.) By this point, it was around 7:30 PM, and my Good Sam Roadside Assistance really had not come up with anything. Mr. Chapman said he would send someone, but it would probably be 12–12:30 AM before they could get there. At this point, I said, "Please send him." Once I knew — or at least thought I knew — someone was actually coming, I called Wes again. Wes once again said, "Call me when you're close." He was very sympathetic to my position. I called him around 3:00 AM, and Wes was there by about 3:30 AM to open the gates and let us in. He stayed until around 4:30 AM getting us parked and set up. I was very blessed that day/morning to have Wes and Tyler, my tow driver, in my corner. Wes did exactly what he told me he would do, even though it ended up being 3:30 in the morning. Thank you, Wes. We won't forget it.

  I was helped by Sergio Alcman he helped me solve a problem that I’ve been having on my Cummings engine ever since I put a aftermarket banks bighorn on my truck. I had multiple symptoms. Loss of power was one of them. Another one was a noise that was coming through that I thought was the fan Clutch I replaced the fan Clutch to novae Sergio came through with one quick listen to my engine pointed out the issue and I am very thankful for him in this team. Anybody who has a large diesel Cummings engine? I recommend this group of people over anybody In San Antonio.

  How about package your gaskets correctly, DEF doser gasket inside of a exhaust manifold package. This is why nobody likes parts people.

  Tried to go here for my trucks heater hoses. First time there the guy asked for my vin number which I didnt have. Make and model wasn't good enough. He said to come back with my Vin number to look up the hoses. Second time there, with the Vin, the guy at the parts counter said they dont even sell heater hoses and sent me elsewhere. Wasted my time. Wish they would have just told me they dont sell heater hoses the first time instead of telling me to come back with the Vin. I will never waste my time with these people again.
