We camped in steady heavy rain last weekend. Our HTT does not leak! Condensation is not an issue using our electric water collecting dehumidifier. When we take down in the rain we just lay towels or dirty laundry on the wood deck where the tene end rests and set up and dry out when we get home running the dehumidifier. I understand your concerns when dry camping with no power. A hybrid is easy to ventilate as you can ope3n each end. We have had ours for alot of years and we work with it. Honestly if I could pay cash I would find a non HTT rig. IMHO the negatives outweigh the positives. However I refuse to finance an RV so this is what we have and mostly it is good. Happy Trails
