Dewey-Humboldt drivers put on real highway miles. Most trips of any length mean Highway 69 into Prescott or over toward the Valley, which is sustained speed, sustained grade and sustained heat in summer.
That mileage profile makes preventive maintenance worth more than it is in town. Catching a weeping water pump, a marginal battery or brakes near the end of their life before a long run is a much cheaper day than dealing with it on the shoulder of 69.
What we see on Dewey-Humboldt vehicles
Highway miles wear differently than town miles
Cooling systems, belts, hoses and brakes take the load on the 69 corridor. We inspect those specifically on vehicles that live on the highway rather than just checking the box.
Plan the trip, plan the service
If you are already coming into Prescott, drop the vehicle when we open at 7:30am and pick it up before 5:00pm rather than making a second trip. Call ahead so we can schedule it properly.
Diesel trucks and trailers
Towing on the 69 grades loads transmissions and cooling systems hard. We service transmissions, 4WD systems and diesel engines, so a towing truck can be maintained around how it is actually used.
The 169 and Blue Hills stretch
Between Highway 169, the Blue Hills climb on 69 and the run out toward Mayer, Dewey-Humboldt vehicles spend more time at sustained load than most. Sustained load is what finds a marginal thermostat, a tired radiator cap or a transmission cooler that has quietly stopped doing its job, and those are cheap parts compared to what they take out when they let go.
