I would chime in that towing a 24' enclosed trailer with an expedition ( or similar sized vehicle ) is not well advised. its not about towing capacity / engine power, but more about mass.

If you have that trailer loaded up, and pull with an expedition, it doesnt take much for that trailer to take the truck along for a ride.

I had a properly loaded trailer, and was towing with my 03 expedition with a 24' trailer. some crosswinds and a passing semi got the trailer moving, and we were along for the ride. we were lucky...

i will never tow this size trailer without my 1 ton dually. the towing is night and day.

just another viewpoint.
