My Marmot Pulsar One is single skin, but with an inner tent mesh. I've camped in a fair amount in wet and stormy conditions and have had some condensation on the inner surface and have had condensation when the other weather conditions are right. Its never been a problem to me though, one or two drips a few times on some very bad condensation mornings but nothing more than that. The mesh separates me from the inner tent surface and it offers me a good through-flow of air which I think helps. Also, my outer tent doesn't actually touch the ground, which I also think helps with the airflow. I don't cook and just drink water when hiking, tea and coffee are only consumed in cafes, so the only heat source overnight in my tent is me.
I have a Wild Country Zephyros One as well and that performs well, I use this tent in the colder months.
As an older person, at some point soon I know I will come to the end of my hiking life, I'd like to have a few more years at it but, although I've looked at buying a new tent for some time I cannot decide on one. And I have a self imposed upper money limit as well, which doesn't help me either.
