We've had our HTT for almost a year. We did camped through Oct and into late Nov. We used a small, portable heater (to supplement the furnace, when needed) and we were never cold. We've camped in the rain with no issues. We haven't been anywhere in heat yet, but have several trips planned throughout this summer. Between Reflectix and the AC, I think we'll be fine.
We love our Hybrid -- there's no way we could get 2 queen beds, stove, oven, dry bathroom, and almost 150 sq ft of floor space in a traditional TT..... all under 3500#!
