Trailer & RV Repair in Craig, CO
Stock trailers, flatbeds, campers and toy haulers. We service the bearings, brakes, lights and wiring that keep a trailer safe, and set up the truck that pulls it.
Quick answer
What maintenance does my trailer or RV need?
Before each season, a trailer or RV needs its wheel bearings inspected and repacked, the brakes and breakaway system checked, tires inspected for age and cracking, and every light and wiring connection tested, along with the tow vehicle's hitch and brake controller. Sitting unused is hard on tires, seals and wiring.
What's included
- Wheel bearing inspection and repack
- Electric brake and breakaway system service
- Trailer lights, plug and wiring repair
- Hitch and brake-controller setup on the truck
Bearings, brakes and the Colorado brake law
Wheel bearings are the classic trailer failure. Grease breaks down, water gets past the seal after a boat ramp or a wet road, and a bearing that was fine in October can seize on the highway in May. We pull the hubs, inspect bearings and races, repack or replace them, and fit new seals, at least once a year and before any long trip, or on the schedule in your axle manufacturer's manual.
Brakes matter for the law as well as for safety. Colorado requires every trailer with a gross weight of 3,000 pounds or more to have brakes the driver can apply from the cab, and a breakaway system that applies them automatically if the trailer comes loose. There are exceptions, including two-horse trailers and some farm trailers, but most loaded stock trailers, campers and equipment trailers are over the line. We adjust electric brakes, test the magnets, and check the breakaway battery and switch.
Lights, wiring and the truck in front
Trailer wiring lives a hard life: corroded plug pins, chafed wires along the frame and grounds that rust loose. Dim or flickering lights and brakes that work only some of the time usually come down to a ground or the plug, the same electrical diagnosis we do on the truck, not the lights themselves. We trace the circuit from the truck's socket to the last marker light and repair what is actually wrong.
The tow vehicle is half the system. We install and set up hitches, wiring and brake controllers, adjust the controller's gain for the load you actually pull, and check the truck's own brakes, transmission fluid and cooling before a heavy season of towing.
Trailers come to us from Steamboat Springs, Hayden, Meeker, Maybell and Hamilton, and from Baggs and Dixon in Wyoming. If you need to leave the truck along with the trailer, ask about our free loaner cars, shuttle and pickup.
Built for the Yampa Valley
Around Craig a trailer hauls cattle in spring, hay in summer and elk in the fall, then sits through winter. Most trailer breakdowns we see trace back to what happened while it sat.

What customers say
“Kyle, the service manager, broke down all the pricing for me so there were no surprises and set up a loaner so I had a car overnight. That's how it should be done.”

Frequently asked questions
At least once a year and before any long trip, or on the schedule in your axle maker's manual. Repack sooner after a boat ramp or deep water, because water in the grease destroys bearings fast.
It depends on what the inspection finds: a repack, new bearings and races, or brake parts. You get a free digital inspection with photos and a written estimate before we start any work, so you know the price before you decide.
If its gross weight is 3,000 pounds or more, yes, with brakes you can apply from the cab and a breakaway system. Two-horse trailers and some farm trailers are exempt.
Usually a corroded plug or a poor ground, not the bulbs. We test from the truck's socket through the trailer wiring to find the fault.
Yes: hitch, wiring and brake controller installed and adjusted for your trailer, so it tows and stops safely.
Trailer tires often age out before they wear out. Check the last four digits of the DOT code on the sidewall: the first two are the week and the last two are the year the tire was made. Cracking in the sidewalls or tread, bulges, or years of sitting in the sun are reasons to replace them, whatever the tread depth. Our tire shop can check and replace them.
Yes, on the running gear: bearings, brakes, tires, lights and wiring, and the hitch and brake setup on the tow vehicle.
