I have yet to tow a decent sized trailer with my 07 EL But when i owned my 08 regular length expedition it towed just fine as long as you are within specifications. To me they drive and feel the same. You need to figure out if you need the extra space behind the third seats and which one gives you the necessary payload. Odds are you run a bigger chance of maxing out the receiver hitch (890lbs w/WDH) before anything else. My EL has a yellow sticker payload of 1500lbs and some change, a GVWR of 7900 lbs and I think the rear axle is rated at 4250lbs. It is a loaded 4x4 Eddie Bauer with all the options, in other words just about as heavy as they come. Its a great truck.
