We are looking at a M2 with a 3126 for our rockcrawling team. We have looked at quite a few expediters, but I'm not sure on what the average life expectancy of the 3126 in the long haul. I am familiar with the city trucks, and know that 300k is quite a few on them. What kind of mileage are you getting out of your 3126's? Any advice you can give would be great. We are looking to spend around $18,000.
