About Us


Cowboy Diesel & Automotive is a small town diesel mechanic shop. Rhonda Wilkinson is the owner and manager of Cowboy Diesel. Her and her husband, Eddie, are retired cattle haulers. Five years ago they decided to hang up their keys and open a diesel repair shop for the small town people like themselves. They were tired of the mechanics that took advantage of them when they needed emergency maintenance on the road.

Established in 2019, Cowboy Diesel is in the ideal location for truckers coming in and out of the DFW metroplex. We are a small team but we have a quality service. We have a few mechanics that we will be adding to the team soon!


Rhonda is extremely dedicated to her community within Mineral Wells, she spends countless hours giving back to the Women's Shelter and Animal Shelter. As she was raising her 4 children, she also took in any child her sons brought home if they needed any help. This women's heart is bigger than most.
