Better to find out at home than at 2AM in the woods somewhere. I have always been suspect of these fair-weather tents with almost no rain fly. The sides and bottom need to be very waterproof, along with the seam seal. I usually give my tent flies a good coating of silicone when they show signs of absorbing water, as the factory waterproof coating doesn't always last more than a couple seasons. For seam seal I use Sil-Net, which is basically silicone RTV caulk thinned with a little paint thinner (mineral spirits), but getting the right consistency is difficult so I use the already-made stuff in a tube. For silicone spray I use Kiwi Camp Dry brand. The combination seems to work just fine.
