Custom Trailer & Truck Modifications

Personalizing and upgrading your commercial truck or trailer isn’t just about aesthetics—it’s about functionality and safety. Our custom truck modifications enhance your vehicle’s performance, visibility, and compliance with DOT lighting regulations.

  • Custom Fabrication: Build and modify brackets, racks, steps, bumpers, headache racks, and other steel or aluminum components to fit your operation.
  • Trailer Modifications: Upgrade ramps, tie-down systems, cargo restraints, landing gear, and access points for improved functionality.
  • Truck Accessories: Install mud flaps, fenders, grille guards, mirrors, steps, and other accessories that improve durability and convenience.
  • Electrical & Wiring Upgrades: Add or modify wiring for lighting, auxiliary power, trailer connections, cameras, and additional equipment.
  • Safety Equipment Installation: Install backup alarms, cameras, reflective tape, warning lights, and other safety enhancements to improve compliance.
  • Cargo Management: Tie-down points, restraints, racks, and trailer changes can support the equipment or materials being transported.
  • Additional Electrical Equipment: Auxiliary power, cameras, lighting, and other accessories may require properly planned wiring and connections.

What We Consider Before Modifying a Truck or Trailer

A commercial vehicle modification needs to work with the vehicle instead of creating another problem. Placement, electrical demand, operating conditions, and daily use can all affect how an upgrade should be installed.

Before completing a modification, important considerations can include:

  • Vehicle Fitment: Components need appropriate mounting locations and clearance for normal vehicle operation.
  • Electrical Demand: Added lights, cameras, and auxiliary equipment need connections that work with the vehicle's electrical system.
  • Daily Working Conditions: Trucks exposed to dust, weather, vibration, or frequent job-site use may need more durable components and mounting solutions.
  • Driver Accessibility: Steps, racks, controls, and equipment should be positioned with regular use in mind.
  • Existing Equipment: New accessories should account for components and equipment already installed on the truck or trailer.
  • Safety Requirements: Lighting and safety-related upgrades should be planned with applicable vehicle requirements in mind.

Planning the modification around the vehicle's actual use helps create a cleaner installation and a more practical result.

I called 23 different companies for help with a stranded truck, and Amoretti Diesel were the only ones able to assist. After spending nearly six hours on the phone trying to find help, I finally called Amoretti. Within 25 minutes of ending the call, they had my truck back on the road. Exceptional service when I needed it most.

Our pneumatic lines on our class A coach kept melting and bursting.   They got us in immediately, found a spot that the turbo wasn't connected to the exhaust due to a loose clamp.   They got a new part, welded it on, rewrapped all the wires who's protective mesh had melted and sent us on our way.   Incredibly knowledgeable and so kind.  Could not be happier with their work.
