Skid plates, racks and clearance
Most of Montana’s documented routes are one-lane dirt and graded gravel rather than ledges, so the fabrication that earns its keep is about clearance and durability. The Forest Service says low-clearance motor homes should not drive the Magruder at all and does not recommend trailers on it because of the hairpin turns, which tells you what a long overhang does on that road.
Ask for recovery points rated for mud extraction, a mast mount if you ride BLM open areas, and racks kept low enough to clear the overhangs on Going-to-the-Sun Road.
When a catalog part does not exist for your vehicle, does not fit with what you already have, or is not strong enough for what you do, a fabricator builds it. Steel or aluminum, welded, finished, and mounted so the load goes into structure rather than sheet metal.
They also fix what breaks: cracked mounts, bent sliders, torn brackets and the frame damage that ends trips.
Common work
01Bumpers with winch mounts and rated recovery points
02Rock sliders and skid plates
03Roof racks, bed racks and ladders
04Swing-outs for tires, fuel and water
05Mounts for tanks, compressors and batteries
06Frame and bracket repair
How to choose a fabricator
Metalwork is easy to judge if you know where to look.
01Look at the welds, then at how the part mounts. Recovery points and sliders should tie into the frame.
02Ask whether they design in CAD or build to the vehicle, and whether you get drawings.
03Ask about material and finish. Raw, painted and powder coated parts age very differently.
04Ask if they have built for your platform before. Templates and fixtures save you money.
05Ask how a front bumper affects airbag sensors and crush zones. A shop that has done it properly will have an answer.
What to have ready before you ask for a quote
Photographs do most of the talking.
01Clear photos of the vehicle and the area the part mounts to
02What is already mounted there: winch model, lights, tire size
03What the part has to carry, and how much it weighs
04Steel or aluminum, and the finish you want
05A budget range and your timing
Questions people ask
Custom or off the shelf?
If a well-made part exists for your vehicle, it is usually cheaper and faster than custom, and a good fabricator will tell you so. Custom earns its cost when nothing fits, when parts from different makers have to work together, or when you need it stronger or lighter than the catalog offers.
Steel or aluminum?
Steel is stronger for the money, easier to repair in the field and heavier. Aluminum saves real weight on racks, skid plates and boxes, but costs more and needs a welder who works with it regularly. Many builds use both: steel where it hits rocks, aluminum where it just carries things.
Can a fabricator repair a cracked frame or mount?
Often, yes. Send clear photos with your request. A good shop will tell you whether it can be repaired properly or needs replacing.
