X2Yup, weight in the back and snowtires.
I just added more weight to mine, its cold and supposed to get colder, more snow supposed to come in, truck is parked in such a way that the back end is higher than the front, i took water out in a 3 gallon stock pot and kept adding until it filled the front and started coming out the back, probly about 4" deep at the front of the bed. it should freeze solid tonight and im guessing ive got about 50 more pounds in the back now. will be intresting to see if its a noticeable differance.
Holy post from the past Batman, lol. I gotta say, I think I missed the boat a bit with my answer... So to rectify, I'd recommend getting some Hankook Ipikes or similar snow tire, maybe mount them on some steel rims. You could try just doing the rear tires... And maybe get a set of chains, and keep a couple shovels handy, old shingles can work as a traction aid in a pinch, rough side down.
