You and me both. Had my own snow wheeling adventure and found my lack of a lift had me high-centered three times. Once, we had to winch all but one of the trucks up a hill, while the others I was the only one that needed yanked out with a Bubba Rope.
What chains are those on the front of your rig? I bought a set of the Peerless Z6, thinking if anything would clear it would be those as they're the lowest clearance I could find. Figured if those fit the front, I'd get a set of the Auto-Trac chains for the rear. Were they helpful in the deeper stuff? I'd actually forgotten about them when we hit the trail, else I'd have thrown them on.
