Major overhaul of 16-year-old air brake system, replacing multiple components. Visiting from out of state, I limped into San Diego with multiple air braking problems with my motorhome. Blindly Googling for a mechanic, I picked Carrol Preble based on a couple of previous reviews. He turned out to be a great diesel mechanic, who was very familiar with all aspects of large trucks and motorhomes. Better still, he is a virtual fireball of energy, working constantly, and stays on the job until it is finished, and it’s done right.

To top it off, his rates are very reasonable, and he is upfront and honest about everything he is doing. And, he’s just a nice guy. I only wish I lived closer so he could do all my work. This is the guy you want working for you — A++!
