I would imagine since it is a brand new model there will not be very much response. I believe you are correct in that it is most similar to the 2701SS but with a much nicer restroom setup and second entry. The 2702SS was my favorite when I first started looking at TT's, then the additional space of the 2901SS was brought to my attention by my better half and became one of our faves, then once we finally saw a 8316SS there was no question, that was THE ONE. I really like all the Rockwood Ultra Lites (the bunkhouse types anyway, never looked at any of the RL, RE or RK types, or "retirement" models as the wife and I wistfully called them), they seem to offer the best bang for the buck. And after looking at approx 200 different TT's over the last 3 months I can honestly say that while they are not top of the line, they are nowhere near the bottom...and trust me, I looked at a LOT of bottoms...of which I will not mention any names so as to not offend any owners of said bottoms....
Which brings me to top of the line stuff, I only have three words to describe my experience with those that I did look at, Highly Over Rated.
Good Luck with your 2702, we are about to order our 8316SS as well in the next week or so, they said 6-8 weeks as well.
