Dd15 Detroit engine, 13 SPD Eaton Fuller manual transmission. This truck is currently back in Priest River for the month of January. Engine and DEF system was completely rebuilt 370,000 miles ago, and I have the paperwork for that! Great condition, all tires at 75% and better. Bunk heater, fridge, microwave. Regular maintenance. Extra set of clean DPF filters. More pics for Serious inquiries only!
