G, you didn't quote the most important part:
but above all else be safe. Good luck, have fun,[/b]

I hope you didn't take my commentary as saying you couldn't/shouldn't do it, just set it up well. If you haven't, please invest in a weight distributing (WD) setup with a sway bar. If the EXP has load leveling, that's good, but I'd bet if you check the sticker of your hitch, the highest tow ratings are reserved for a WD setup.

FWIW, I've got a Yukon XL, 3/4 ton with a 496ci (8.1L) that's "rated" for up to 12k lbs. In addition to my 24' enclosed (8k lbs loaded), I recently started towing a 9k lb boat. Here in south Florida, the biggest "hill" I have to deal with is a highway overpass and occassional bridge. My truck gets it done, but it gets one heck of a workout.

Just a sidebar piece of data for anyone else who happens along this thread: "tow ratings" are more a function of engine power/axle ratio/transmission load capacity than they are a "blank check" to go out and tow the max cap in all conditions.

Because we can't say it enough, be safe, good luck, have fun,
Michael
