What Alaska Truck Owners Say
Real customer experiences from truck owners and local businesses across Anchorage.
"Diamond Truck Service handled a complete high-pressure fuel rail issue on my 6.7L Cummins that another shop couldn't figure out for weeks. Diagnosed it accurately the same afternoon, ordered the right parts, and had me back on the road in two days."
"Got a pre-purchase inspection done before buying a used Power Stroke on Facebook Marketplace. They found high crankcase blow-by and pending EGR codes that saved me thousands of dollars. Absolutely indispensable before buying any diesel in Alaska."
"We rely on our food truck generator and diesel chassis every weekend during the summer. DTS has maintained our equipment with zero unexpected breakdowns. Reliable, straightforward guys who know diesel inside out."
