Our Service Department has 14 bays, frame bay and paint shop. We service all types of semi-trailers, such as grain hoppers, walking floors, lowboys, belt trailers, end dumps, belly dumps, dry vans, reefers and flat beds, install and repair wet line kits on tractors, and do all types of hydraulic repairs.


Trinity is a Certified Texas State Inspection Station and also performs FHWA Inspections. We install and repair tarp systems, and paint trailers to customer specifications. Trinity works with insurance companies and adjusters for minor and major repairs. In some cases we can save some or all of your deductible. Trinity has two mobile service trucks that are equipped to do minor repairs, PM and FHWA inspections at your location.
