I just think they're different animals. Don't know what the OP considers to be "touring", but I don't really think of the R3T as a true "Touring" bike. It's a fine bike, but it's not in the same league (in terms of features) as the BMW, or Goldwing. I just think the OP should spend some time on one before dropping the coin.
I'll clarify. I would use this bike for the following:
1. Solo, multi day travel, usually a week to 10 days, 2 or 3 times a year.
2. 2-up, daylong road trips.
You're correct about the features as well. The 'LT has lots of "bells and whistles" which make a long trip more enjoyable. Although, I've taken the Scrambler to Florida on a 5 day trip and really enjoyed it. Wouldn't do it again though (at least, not while a bigger bike is available).
I will try and get some additional riding time on an R3T before making any decisions, but I understand that Triumph has terminated its truck demo program. I really enjoyed those things.
I still think an R3T is in my future. Maybe next year.
Thanks for the feedback.
