2014 Ford Expedition Towing Capacity

I do not understand why you need 3 rows of climate controlled space for 2 people. The second row of crew cab pickups offers more people space/legroom than any SUV. They cost about $10k less than similarly equipped half ton SUV. $200-2000 will cover the truck bed for various levels of security, functionality, and appearance.

Anyway, the Epy limit for a couple is...the receiver at 920 pounds. That's about a 7000 pound loaded and 6000-ish dry RV. Lots of choices of RVs in that range. You just need to figure out what is more important to you.
