Andres Torres
Can’t say enough good things about Pal-Pro Fleet Services. One of our trucks went down with a bad temperature sensor. We were stuck on a job site and called Pal-Pro — they had a tech out to us fast. Adam diagnosed it quickly, had the parts on hand, and got us back up and running the same day. No towing, no crazy downtime. Honest, professional, and really knows diesel trucks inside and out. Highly recommend these guys!
