I am towing a 2,800 pound camping trailer here in Colorado (including 8K plus passes) and the X3 has been an excellent choice for towing. In terms of pulling, braking, stability, and efficiency it is far superior to my Cherokee with a 4.0 and factory towing. I credit a lot to the 6 speed manual and always being able to be in the correct gear. I do question long term durability, but I'll find that one out in the future as I only have 50K miles on it. I think that the X3 is too often dismissed as not being towing capable. Looking forward to a diesel X3 that would be even more fun.I live at altitude (approximately 6K feet above sea level) with the nearest town to the west just 45 miles away and at 7200 altitude. There is a summit between at 8640 feet (highest point of the old Lincoln Highway (now I-80) from coast to coast). The car dealerships love the folks that come through here towing things, as a large percentage of them fry their transmissions on the hills. Of course, that's altitude and hills. Nevertheless, you sure you want to tow that boat with an X3?
