I am heading to Colorado with my family. We will be towing a trailer with a Jeep on it. The loaded trailer weighs 6500lbs. I have a weight distributing hitch, and Tekonsha brake controller. How well will the Expy EL pull this load?

I have an 08 F-350 Diesel that I know would pull it better, but fuel cost and comfort make the Expy a better choice for this family trip. Will I be pulling my hair out on the Colorado mountain climbs?

Who has recent towing experience pulling 6500lbs? Most of my grades will be in the last 200 miles. This is a 1200 mile trip ending at an elevation of 10,000ft.

What do you think????

Thanks,
