Like a tank actually and I don't have chains. That storm, pictured, dumped 24" of snow on us and I had no issues. Loaded, I'd say I'm probably around 24,000 lbs.
I plow a state road with this truck and then jump onto commercial work after that where I run another truck and Bobcat. 4WD, and I own two, is over rated for snow. Sure, driving around is good but nothing beats just having weight. The large dump trucks plowing highways aren't 4WD but have weight on their side. Take the weight out of this truck and its not going to do a lot.........regardless of 2WD or 4WD.
