I bought the Kodiak Deluxe 10x10 from Cabela's a month ago, and used it in the TN mountains this past weekend. I outfitted the Kodiak with a 17 oz 10' x 10' canvas tarp as a floor saver, and on the ground underneath the tent I placed a standard poly tarp (10' x 10').
This was the first time I have used the tent, never getting the time to erect the tent in my yard and "season" the canvas and seams as is recommended by wetting the tent and letting it dry a couple of times. I didn't have time to do this step, plus the forecast was for dry conditions.
I set the tent up for the first time in about 30 minutes. Driving the stakes in the ground took the longest. The rest was a piece of cake.
The rains came about 4pm on our second day in camp. The ground in the campsite was dirt, with some pea gravel areas in proper campsite "pads". I was on one of those campsite pads. It rained hard for about 12 hours all total Thursday afternoon to Friday morning and then let up. Sunny skies came right after the rains, drying most everything out.
The tent never leaked a drop. While away from the tent for a while a small pool collected right on top of my thermorest and cot, but that was because I left the rear door window flaps unzipped by accident.
The tent canvas was muddy and splattered with dirt along the bottom, and the whole thing was damp on the outside when I folded it up yesterday morning to load it up for transport. I folded the tent so the floor was to the outside and just tossed it on the trailer and covered it with a tarp.
When I got home I put the tent in my garage (it was raining) and hoisted the roof up to the rafters by the metal grommet tabs sewn into the 4 corners of the roof. It's hanging there now and is dried out enough to brush off the dirt. I hope this doesn't put too much stress on those grommet tabs, but its the only way to "erect" the tent in my garage to dry it out.
Anyway, tent gets an A++ from me!!
