Alaskamax, I doubt your truck from the north slope has a whole lot of miles on it, its hard to rack up a lot of miles during white outs, but they used to keep the engines running all the time when the temp got really low, so a lot of those 6000 hours is probably idle time, non the less thats a lot of hours, if the average speed was 30 mph that would amount to 180,000 miles, maybe when I drive up to Alaska next time I'll look you up and see this truck. In fact I'd really like to visit the plant at Prudo Bay since some of the equipment I designed t has been there since the 70's. I'd like to see how it still looks inside those modules. I may just have to check into that before I head up there. Probably be 3 or 4 years away yet, before I'll have the time, but I'm going to make that trip on day.
