We had a Woods 9x12 canvas tent when I was a kid. Annual camping trips, some in gawd-awful pouring rain for a week.
I bought the same tent for my family. I've lived in a Woods Prospector shack tent for several months for several summers.
I'm so pessimistic that I'll say that they all leak, maybe not today but tomorrow. Hindsight tells me to buy a really big tarp. One end to act as a rain fly
and the other end as a outside rain shelter so you can get out of the tent and stay out of the rain.
The Kodiak you're looking at is a really nice size and design. I'd just be ready to cover it up. Don't believe that you need the model with the extra windows.
