To the OP, I would only say be aware that wind resistance will likely be more limiting than weight. For that reason alone, you'll be best served by some sort of pop up. A full-height/width TT no matter how little it weighs will suck up so much power you won't like towing it.
good point - I will say I have towed 2 popups up to 5000 miles round trip, I always appreciated not having to deal with the wind.
