What Our Clients Say

Real feedback from businesses we’ve helped get back on the road

ermias kassahun
Excellent service and very honest people. I came in with a driveshaft/carrier bearing issue causing vibration on my truck, and they stayed after hours to help me. Small family-owned shop with great courtesy, professionalism, and customer service. They explained the issue, showed me the work, and made sure everything was done properly. I’m very satisfied with the repair and thankful for their help. Highly recommend this shop for driveline and truck repairs.

John Carroll
John with J&A Fleet was awakened in the middle of the night. I waited less than 15 minutes for his arrival. He had me up and running within seconds. Showed me some unique tricks for future issues. You cannot go wrong with folks like John. Thank you so very much for making a difficult time seem so easy. Will not forget.
RFS Billing
Went to TA and they were going to charge over 3 k said we needed a 5th wheel plate. J&A techs found the actual problem and had us ready to go in less than an hour. Very honest shop
Nam Phamtran
Talked to John about paying for him to inspect a truck, I told him the specs on the truck and he told me over the phone that it was not worth the money that they were asking for the truck. He was honest even though he would be losing out on the inspection fees. What a great guy and company!
Adam Ryder
