Custom Modifications in Chino

The short answer

OCRV Center plans and executes custom modifications on RVs, trailers, and vans in our Yorba Linda shop, from layout and structural changes to off-grid prep and equipment integration. Most modification projects run from $500 to $40,000 depending on scope.

Ballpark: $500 to $15,000+

A custom modification is rarely one trade. Cutting in a new window, relocating a wall, or mounting a rooftop deck touches fiberglass, framing, wiring, and sealing all at once, which is exactly why these jobs belong in a full collision and structural shop instead of split across vendors. We plan the whole change, then fabricate and integrate it under one roof. All modification work is in-shop only at our Yorba Linda facility.

Modifications we take on

Owners come to us when a project crosses too many trades to hand off piecemeal. Converting a bunkhouse into an office, cutting in a larger window, adding a rear patio or deck, or hardening a rig for boondocking all mean opening up a wall or roof, rerouting what is behind it, and resealing the envelope so the change does not leak. We own the whole sequence so the seams between trades do not become the weak point.

Because we already do collision, fiberglass, structural, and electrical work in house, a modification can pull from all of it. That means a new opening gets framed and reinforced, the skin gets cut and rebonded cleanly, the wiring gets run to code, and the exterior gets resealed to factory standard before the rig goes back out.

  • Interior layout and floorplan changes
  • New windows, doors, and roof openings cut and reframed
  • Off-grid and boondocking prep, including battery and inverter bays
  • Rooftop deck, patio, and accessory mounting
  • Suspension and ride-height accommodation for added equipment
  • Equipment integration for work, sport, and adaptive use

Planned as one project, not a stack of add-ons

Every modification starts with a plan, because the order of operations decides whether the result is solid or a future leak. We map what is inside the wall, roof, or floor before we cut, reinforce any opening that carries load, and sequence the trades so sealing and finishing happen at the right step. A written estimate follows the design so you know the scope and the stages before work begins.

We are candid about weight, balance, and structure. If a planned change would overload an axle, weaken a roof, or compromise the envelope, we say so and offer a version that holds up, so the modification adds capability without creating a new problem down the road.

Sealed, finished, and road-ready

The difference between a clean modification and a regret is the finish work. Any cut we make in the fiberglass or roof gets rebonded, gasketed, and resealed to factory standard, and any new opening gets trimmed and weatherstripped so it stays dry. Inside, we match materials and hardware so the change blends into the coach, and we road-test the result before delivery.

  • Cuts in skin and roof rebonded and resealed to factory standard
  • New openings reframed, reinforced, and weatherstripped
  • Wiring run and protected to code for any added systems
  • Interior finishes and hardware matched to the existing coach
  • Inspection and function check before the rig leaves the shop
Questions

Frequently asked questions

Can you change the floorplan or layout inside my RV?+

Yes. We relocate walls, convert bunkhouses, and reconfigure layouts in our Yorba Linda shop. Because the same shop also handles the framing, wiring, and resealing the change requires, the whole project stays under one roof rather than split across vendors.

Can you cut in a new window or roof opening without causing leaks?+

Yes. We map what is behind the wall or roof first, reframe and reinforce the opening, then rebond and reseal the skin to factory standard and weatherstrip the new opening so it stays watertight.

Will you tell me if a modification is a bad idea for my rig?+

Yes. We are candid about weight, balance, and structure. If a planned change would overload an axle or weaken the roof, we will say so and offer a version that holds up rather than build something that creates a new problem.
