I have a 28' extra-height trailer (fits one dragster, just reconfigured it so I can get two in there), and tow with a 2500 diesel pickup. Tows great.
If you look at the towing specs for most 3/4 vs. 1 tons you'll see that the 1 ton dually only gets you about 1000 lbs more towing capacity (on a tag trailer). I did a ton of research and ended up with the 2500, and I'm glad I did. If I was towing 5th or goose, I'd be at the 3500 in a heartbeat, but on the tag, the difference is minimal. And the extra set of wheels makes the dually a bear to park/maneuver as a daily driver.
Of course, being a Ford guy, you'll want to convert all that to F250 and/or 350
