Custom Trailer and RV Modification and Upgrades — Laval
Your trailer doesn't do exactly what you need? We build custom modifications and upgrades to fit it perfectly to your use, at our shop at 1870 rue Cunard in Laval. We modify every type of equipment: light trailers (utility, enclosed, open), medium-duty trailers — goosenecks and fifth wheels with axles up to 18,000 lb per axle — and RVs. Raising sides, adding ramps and winches, adding or upgrading axles, interior fit-out, lighting, braking and suspension upgrades: every project is designed with you, respecting safety standards and real capacity.

Modifying a light trailer (utility, enclosed, open)
Light trailers lend themselves to a host of upgrades that make them more practical and versatile day to day.
- Raising sides, adding cages, walls or roofs
- Installing loading ramps, doors and tailgates
- Fit-out (workbenches, storage, partitions, equipment and tool mounts)
- Adding tie-down rails, D-rings and anchor points
- LED lighting and wiring upgrades
The result: a trailer built exactly for your trade or hobby — more efficient and safer.
Modifying a medium-duty trailer — gooseneck and fifth wheel
On medium-duty trailers — gooseneck and fifth wheel — modifications often involve capacity and the hitch. We always work in line with the axles (up to 18,000 lb per axle) and the structure.
- Adding an axle or upgrading axles to increase load capacity
- Installing or converting a gooseneck / fifth-wheel hitch
- Upgrading brakes and suspension to match the intended load
- Fabricating heavy-duty mounts, winches and tie-down systems
- Raising and reinforcing the deck for specialized loads
Every upgrade respects the trailer's real capacity and safety standards, so you can haul more — no compromise.
RV fit-out and upgrades
An RV is better when adapted to the way you travel. We build fit-outs and upgrades that add comfort, autonomy and safety.
- Adding or rebuilding bike racks, exterior storage and cargo carriers
- Electrical upgrades: wiring, outlets, solar panels, batteries
- Hitch, sway-control bar and jack upgrades
- Reinforcing attachment points and repairing structures
- Custom accessibility and storage adaptations
We design each RV fit-out with you, for a practical, durable result.
Braking, suspension, axle and electrical upgrades
Beyond the body, we improve the systems that keep your trailer running safely, whatever its type.
- Braking: adding or upgrading electric or hydraulic brakes, brake controller, breakaway brake
- Suspension: switching to reinforced leaf-spring or rubber suspension, ride-height correction
- Axles: adding, replacing and upgrading to increase capacity and ground clearance
- Lighting and electrical: LED conversion, full harness, connectors, charging outlets
Every upgrade is sized to the real use and capacity of your trailer or RV, in line with Quebec standards.

Frequently asked questions
Can you add an axle to increase capacity?
Yes. We add or upgrade axles and upgrade the brakes and suspension accordingly. Final capacity is still dictated by the axles, tires and hitch — we advise you on what is safe and compliant, especially on medium-duty gooseneck and fifth-wheel trailers up to 18,000 lb per axle.
Do you modify gooseneck and fifth-wheel trailers?
Absolutely. We install and convert gooseneck and fifth-wheel hitches, raise decks, add winches and heavy-duty tie-down systems, and upgrade brakes and suspension — always in line with the trailer's structure and axles.
Do you do RV fit-outs?
Yes. We handle electrical upgrades (wiring, outlets, solar, batteries), hitch and sway-control upgrades, custom mounts and storage, and reinforcement of attachment points.
Does a modification affect SAAQ compliance?
We design every modification to respect safety standards and the trailer's real capacity. We can also verify compliance and prepare your trailer for SAAQ mechanical inspection after the work.
