The Tow Vehicle Question, Of Course

Good morning folks:

I've posted before looking for Trail Mini input and also towing questions regarding a 2720. Now, our attention is directed solely towards the Elkmont. I wish there was a shorter model than 24' + but it is a beautiful trailer and would serve our needs for the next 15 years.

My question is my tow vehicle and mountain towing from the SF Bay Area through the Sierras and the Rockies to eastern Colorado and back each year.

The weight of the Elkmont would be around 3000 lbs. before another 600-800 lbs. of "stuff" is added. Is a 2008 Ford Explorer Sport Trac with a 130" wheelbase, 4.6 liter V8, and 7000 lbs. towing capacity OK for the frontal area of an upright trailer for the elevation changes we would encounter yearly on our SF/Colorado trips?

Thanks for any feedback!
