Maybe you need custom racks for your specific equipment, extra tie down points for your loads, or a complete conversion to make your trailer work for a new purpose. Keep Them Rolling Trailer Repair provides custom trailer modifications and upgrades across Morris County NJ. We design and build custom solutions on location that make your trailer work better for your specific job. ## When You Need Custom Modifications Every trade and business has unique hauling requirements. Landscapers need specific rack configurations for mowers and equipment. Contractors need custom tool storage and tie down setups. If you are converting a trailer from one use to another, modifications make the transition work. Adding electrical outlets, interior lighting, or upgraded wiring for a work trailer setup is a common request. Upgrading from standard components to heavy duty parts prepares your trailer for increased loads. Custom ladder racks, lumber racks, pipe racks, and equipment mounts all fall into the modification category. If you can describe what you need, we can build it. ## Our Custom Modification Process We start by discussing exactly what you need and how you use your trailer. We look at the trailer itself and design a solution that works with the existing structure. We fabricate custom brackets, mounts, racks, and components using steel and aluminum depending on your requirements. All welding and fabrication happens on location at your property. We install everything securely, test it under real load conditions, and make adjustments until it works exactly right. If the modification involves electrical work like adding outlets, lights, or charging systems, we handle that as part of the project. You end up with a trailer that is set up specifically for your job. Most modifications involve metal work. Our [custom welding and fabrication for modifications](/structural-welding-and-fabrication) handles brackets, mounts, racks, and anything you can design. Adding outlets, lights, or cameras? We also handle [electrical additions and wiring for upgrades](/trailer-wiring-repair). ## Custom Modification Cost in Morris County Custom modification costs depend on the complexity of the project, the materials required, and the fabrication time involved. A simple set of custom mounting brackets is on the lower end. A full custom rack system or trailer conversion is a larger project. We discuss the scope with you upfront and provide a clear estimate before starting work. No surprises. Fleet customers with 3 or more trailers save 10% on custom work as well. ## Why Choose Keep Them Rolling We have over 30 years of experience building custom trailer solutions.
