They checked the transfer and breaker boxes. They narrowed it down to the apu, which they do not work on. Even though they did not fix my issue, I was willing to pay them for their time, but they refused. They will get my business on the Truck and the RV side from now on!

Our 2018 Nissan Titan with a 5.0 cummins turbo diesel spun a crankshaft bearing on our way to Ohio. We took the truck to the "A" team at "DOT" and right from the start the were honest and fair. They scoped the engine and told us exactly what was wrong with it with photos. We ordered an engine off of Ebay and when it arrived it was in sub par condition to say the least. They documented it for us with photos and an an honest opinion of "we cant, with a good conscience, install this engine in this truck" We sent it back and got a full refund thanks to John and the "A" team. Unfortunately we had to sell the truck due to hard to find parts and aggrevation. I Highly recommend these guys to anyone with an issue with their deisel. Hopefully it's not a Titan. Thanks Again John
