I agree, the Durango is a good choice. About 6000 lb tow rating with the V6, I believe. It feels peppy with the way the gears are spaced on the 8 speed transmission. You might also consider the Toyota Highlander, with 5000 lb rating (V6). I've done a ton of towing with mine.
Fuel economy, if important to you, points toward another popup or a molded-fiberglass trailer. A conventional, boxy TT will drag you down to 10-12 mpg in all likelihood. A low profile, rounded Scamp, Casita, Lil Snoozy, Parkliner or similar trailer will probably net you 15-17 mpg. A popup, probably 18-20 mpg. Parkliner is sold from the factory in NC, Lil Snoozy from their factory in SC... not too far from you. Another possibility would be a Trailmanor, but they are considerably heavier (and higher priced).
