>Still, it would be difficult for me to buy a 86" length tent without laying in one first. I guess a way around this would be to find an 86"L tent of a major brand at a local store, lay in it, and see if it feels right.
Ian, that's not a good test and in this case specifications lie. Most floor end walls on dome designs, Big Agnes included, slope inward and cut off usable space and volume. If you can find a tunnel design with vertical end walls, that's a much better test. The Scarp 2 floor end walls are completely vertical to 16" above ground (not to mention the completely vertical long side walls). You lose a lot more than 4" off the ends of your Big Agnes floor due to the inward slant. The 86" Scarp 2 usable length is greater than your 90" Big Agnes usable length and there is absolutely no question that you will fit just fine in the Scarp 2.
