Well from what I've been reading, the first step is definitely a vacuum gauge regardless of the gearing and transmission. I just might be steering to the 700r4 - np208 - locking hubs configuration.

I like the idea of just keeping the hubs locked in the winter months and unlocking them in the warmer months. Being honest with myself, I have got stuck in snow way more than in mud. Mainly because if it seems muddy, I stop and ask myself whether it is worth it. (stuck, get out walk, get a tractor, or go to the neighbors and ask for their tractor all the while in a soupy mess). Snow isn't as bad.

I'll chew on this for a bit. Whatever install I do, I will be back on this thread to update what configuration gave me the best fuel mileage. I plan on working on the truck once the weather warms up (currently -19C or -2.2F haha).
