Graham, thanks very much for your lengthy and comprensive post on the A/T Teardrop. As you know I have been on the fence ever since I saw one at the 2009 Expo. I know it would be way superior to my current trailer for serious off-road trips, but the small interior would possibly prove too cramped for a live-in use. I keep telling myself I won't live there; only sleep there. But as I write this I am in my trailer during a prolonged rain here in Central Florida and wondering how I would handle it with the small Teardrop. The Oasis would be way more roomy but set up would be a problem for me and it's still a tent, even with the best material available. I like the security of the solid walls on the TD; keeps prowlers at bay (2 & 4-leg), solid walls to lean on, place to mount things to make it more like home, survive about any storm, no canvas flapping, no mildew issues or waiting to dry out.
I have a concern with the TD you also mentioned.. how to cook in wind/rain. I envision a hooded rainfly over the rear like in an old covered wagon and a HD awning side mounted with a add-a-room. Mario and I discussed the last option some time back.
I have heard there are several A/T Teardrops in use now and would like to hear from other owners about their experience.
