Look for an LT (light truck) tire with a load range E rating. They might ride a bit harsh without a load, but they are great for towing. I have had both Firestone Destination A/T (about $225/ea) and Yokohama Geolandar A/T (about $205/ea) and I liked the ride and handling of the Firestones (despite my 1999 Ford Explorer Firestone tire recall fiasco...but that's another story). You can also look into upgrading the stabilizer bars which will help with some of the roll.
