The perfect snowmobiling,family,work truck is a 07 or older 2500hd chev or gmc equipped with the allison 5 or 6 speed(6spd in 06-7)5spd auto in years 01-05 and the 8.1 big block gas.You can find a nice under 40k mi,leather,sunroof,four door,xm for $20k+-.Lots of power,starts easy at -20.
8.1 gasser really sucks at mileage. Yes the power is very good but not worth it. I would pick Duramax over 8.1 gasser anytime at a blink of eye. My friend has it, is getting 7 mpg pulling trailer, 11-12 mpg empty... My 05' Duramax gets 12-15 mpg pulling trailer and over 20 empty, that is after I added Edge Juice with attitude and 06' turbo mouthpiece. I would not go back to ole' gasser days. Love the power and torque of Duramax to death!!!!!!!!!!!!
