I was having voltage issues and needed the alternator checked. They pulled the truck in within 20 minutes, checked and diagnosed the issue within another 10, and were able to get the truck back up and running on the same day. I use my truck daily for work, so downtime isn’t something that sits well with me. Everyone was helpful and responsive. Will definitely return if and when the truck needs anything done.
