Traveling with my fifth wheel trailer to see family in Amarillo. We did not have power to trailer brakes. Contacted another shop that could not fit us in, but recommended TWA. Tyler accepted our appointment, jumped right on the problem, addressed several issues and tested everything on a trailer at the shop. Couldn’t ask for better service and very grateful TWA was willing to help us on such short notice. Much, much thanks to Tyler for saving our trip by ensuring we are towing safely!Posted on Google Lorelie ThompsonTrustindex verifies that the original source of the review is Google. If you're in the Amarillo TX area and needing diesel work, I highly recommend TWA Diesel Performance.
