UPDATE: We had our annual family campout last weekend and the new Cooper tires worked well. All 4 at 80 psi; same for the FW, as we were running a bit heavy. Towing at +/-62 mph. Tires are very quiet, though there was still a bit of "hunting" along the pavement seams, so I did have to be on top of my driving. Was muddy getting out, but had no problems, even in 2wd. Very slopping going in, however, and was in 4LO simply to keep my speed down through the ruts and holes.
So far, I'm happy with the Coopers and hope they last better'n the BFGs.
