Steve - you should be drivin the burb in this stuff - my TF panel was great in snow, w/ no added weight in back - my 58 longbox does fine w/ a couple 5 gal containers of water back @ the tailgate, and the new 700R15 snow treads

narrow lug tread is best for traction - still light snow here, tho' they say it's gonna turn to rain by morning
