yeah, the 4x4 works great, with the 4.10s and 33's and the granny low in the ZF, low range really crawls. Had to use it a couple times actually.
I am super pleased with the milage. This is truck is actually cheaper to drive than my explorer was, even with the higher cost of diesel. If I have both tanks full, I have a 7-800 mile range. Plus I have the advantage of an 8ft truck bed and being able to tow almost anything I want. The extended cab is nice too, anything I want to keep dry I can throw back there, and its within easy reach.
I plan on adding a toolbox after my next paycheck.
This actually will be very useful in the next few months as I am in the process of moving to the Anniston, AL area for my new job.
I probably should start another thread on this, but this way all my stuff is in one place.
