I'm with you Mark.... bums me out to realize this is really the one kind of driving that I am simply not likely able to do much of (mine does great in the snow, but sand?) I would still very much like to do some testing sometime and see just how my dually 19.5's would do. The tiny bit I have hit in Moab in search of camps sites have been OK, but I'd need to be REALLY prepared to even begin to see how it would do on a beach, probably with a few other rigs around for help. I was oh-so-tempted to drive out onto the sandy flats along the Green River by the Gates of Ledore, but having a long drive in front of us to get home, and knowing we were on our own there...prudence won out.
Oh well, like Steve points out, it is all about trade-offs.....
