I'm considering a purchase of the Nismo 4x2 KC to use off-road for work (large construction jobs, some dual track trails, but no serious "technical" 4-wheeling). How does the 4x2 Nismo handle the off-road with the locking differential activated? Am I better off just purchasing the 4x4? My current truck is a 1998 Ranger XLT 4.0L 4x4 with 175,000 miles and has served me well up until about 3,000 miles ago. Thanks for any feedback.
