Testimonials

"Tom knows diesels inside and out. He'll leave no stone unturned and will let you know the good, bad, and the ugly. Tom is very knowledgeable and willing to take the time to explain everything in great detail so you can make a fully informed decision on repairs. A simple repair for me turned in to a 40 minute discussion about diesels. Thanks Tom!"
Michael Caldwell

"This is my new Diesel shop for my 2008 Ford F-350. I had a full tune-up and four new tires (hard to find right now) installed and my truck drives like new! I'll definitely be back. Thanks guys."
Josh Smith

"Tom 'Big Dogg' may be a Ford Diesel specialist, but that doesn't mean that's all he can work on. Tom helped me out with my Cadillac CTS-V Transmission. Getting it out for us to rebuild and stabbing it back in. With top of the line equipment, a clean, organized shop, and decades of experience, I wouldn't hesitate to bring any of my vehicles here. Not to mention, you're guaranteed to get some laughs while talking with Big Dogg! 😆 Thank you sir, until next time!"

"Tom and his team are amazing. my 6.7 blew the motor and he went above and beyond to get it replaced. Communication was top notch and had it finished before he said it would be done. One week for a new engine is unheard of, other shops were 2-3 weeks out and i dropped it off same day. He is my go to diesel shop, most knowledgeable guys. If you own any ford diesel do yourself a favor and call Tom!! Thanks guys!"

Bring your Rig to Big Dogg’s and Tom and his team will get it straight for ya and that’s a fact. Brought my 2020 F250 Diesel to Big Dogg with some serious transmission problems. Gears all over the place, hard shifting, skipping gears, error codes. They diagnosed the issue, provided options and advice for next steps forward. Communication while my truck was there was great and on point.
Ended up approving replacing the Transmission with a new OE ford 10 speed.
Big Dogg’s shop was slammed with work and limited capacity with team on shift yet Tom and his team managed to get my stuff on order and wrench on my truck to get it back in a few days.

"These guys are the best, they were able to fix my 6.4 Powerstroke when several other shops couldn't. Tom promised me he would get it right, even though it would take time. He got it purring and only charged me for a fraction of what he had to do to solve the mystery, even met me on a Saturday to pick-up. Only good things to say about these guys."
