P.S. My 31DS has the upgraded 7500 lb tow capacity. The jeep is 5,000 lbs empty. Gas mileage suffers towing at about 7.5 to 8.5 mpg, but we are mostly in the mountain regions (Washington, Oregon, Utah, Idaho, Nevada, Arizona so far). It's a V10 gas, not a diesel, so on long pulls, plan on letting it rev and taking your time, but we have done up to 8,000 feet and pretty steep in places and it will get there....just not as fast.
