"J&A are awesome. I was on vacation with my husband & kids when the air conditioning in our van stopped working. The Texas heat was unbearable. JD was able to flush and charge the system right from his truck. He and his wife, Ashley, made us feel so comfortable and saved our vacation."

"We didn't know what to do when our RV fuel pump failed us late at night. JD had a truck full of all the required tools and equipment to get us back up and running fast."

Possibly the single BEST experience with a mechanic in my 10+ years as a fleet Owner/Operator. I was in a bad spot and at my wits end trying to repair an issue with one of my Freightliners. Didn't feel confident in any of the area repair sites suggested to me and got JD on the phone by chance. I have to say that he was reassuring from the start. In less than 24 hours he had my truck up and running without the cost that other repair shops were quoting me just to open the hood.

"I can't tell you enough how happy I was to find a good reliable and honest shop. Highly recommend if you're in the Bastrop/Austin area. Great customer service from JD & Junior. These guys don't play around and had me in and out quickly while almost every other shop in Bastrop was booked for days or overpriced."
