Customer Testimonials

Customer Testimonials

"Excellent service, friendly technician, explained everything  he was doing and he was as quick as the procedure allowed. I'd recommend Big Rig Fixer to everybody."
- Robert

"Big Rig Fixer has not backed down from any challenge I've brought them. Hydraulics issue with the winch on my millitary surplus vehicle - fixed! Issues with the air system - fixed! If Pat and his crew don't know how to fix it, it can't be fixed. Not only is the crew here knowledgeable, but they take care of their customers. I would highly recommend Big Rig Fixer for your big truck repairs."
