Serving Cascade
Cascade sits on the Missouri River along Interstate 15, between Great Falls and Helena. The country around town is ranch land, with river bottoms, open benches and the foothills to the west. Many trucks here split their time between interstate miles and gravel ranch roads, often with a stock trailer or flatbed behind them. The river corridor can funnel strong wind, and winter cold settles hard on the valley. Freeway speeds with a loaded trailer heat up cooling systems and transmissions, while ranch roads shake loose wiring and wear out suspension parts. Spring mud and fall hauling season both put extra load on brakes and drivetrains.

Why Cascade customers need this work
For a ranch truck around Cascade, the common trouble spots are the cooling system, the transmission and the brakes, because towing on I-15 and pulling up out of the river bottom loads all three. Diesel engines also need clean fuel and working injectors to pull without smoking or losing power. Trailers take a beating on gravel, so lights, plugs, brakes and hitches need regular attention. Catching a small problem early, like a slow coolant leak or a flickering trailer light, usually keeps it from turning into a breakdown on the highway shoulder.
