I have a Lite Fighter tent that I managed to snag off the books, best tent I've had, used in many field ops and on personal backpacking trips.
In heavier rain environments Ive had better experiences using a Walmart hammock, poncho / tarp and sleeping in a waterproof bivy sack. I recently invested in a Hennessy Hammock and it's been pretty killer. It's retard proof to the point where I set it up completely blind in a light restricted environment, and once more under nods.
