About Blacktop

Brennan Parks answers the phone, drives the service truck, and turns the wrench on every call himself. Below: the story, how to reach us, and recent work from the road.

Brennan in the cab of the service truck — owner-operator running every call himself

Built on Diesel, Fueled by Integrity

Blacktop Mobile Truck Repair was founded by Brennan Parks, a diesel tech who grew up turning wrenches and learned early that his passion is anything with a motor. After years in the industry, he saw too many roadside repair companies cutting corners, charging outrageous fees, and leaving truckers stranded. That's why he started Blacktop: to give drivers a mobile repair option that actually puts their needs first.

Show up. Tell the truth. Do the job right.

We operate within a 75-mile radius of Russellville, KY, to bring professional diesel repair directly to you. Whether you're roadside in Nashville or parked in a fleet yard near Bowling Green, we make it easy to get the repairs you need. Transparency and honesty; 1-year parts-and-labor warranty when we supply the parts; hands-on service from a tech who genuinely loves what he does.
