Customer Testimonials
Julian Burton
I was stuck in the middle of nowhere, which was 90 miles away from his shop. I got a tow, fixed my problem, and I was on my way without delay. Efficient team.
Paul Diegel
What others have said - I had a weekend trailer problem passing through town and Anthony fixed me up quickly at a reasonable cost. Met me after hours, showed creativity and good judgement required to fix a 68 year old trailer, communicated really well, and was super friendly. Highly recommended.
