We often use an '02 F-350 in 4LO to pullstart a maintainer/grader. Those trucks can pull a semi out of a jam if needed. I came close to getting stuck in my Z-71 yesterday. Packed the wheelwells with so much sticky mud, I couldn't even turn the steering wheel and had to scrape it off by hand. The Bronco just walks right thru the same stuff in 2HI.
I found a small challenge for it today--slick mud. Very easy to turn around on a dime, tracked fairly straight for once. I had a problem in the past with the Bronco "snaking" in this mud, even to the point of my friends laughing that I could not drive a straight line. Fixxing the radius arm bushings and the steering shaft solved that problem!!! A 4wd Dodge Dakota didn't make it 20 feet before getting stuck. I warned him not to try it, so he got no help from me!!!
