Has any one used the wall tent from cabelas? We are looking to go to montana elk hunting and looked at army wall tents but the pack weight was too much to carry in. There will be about 8 of us going. How big sould we looking at? The one at cabelas is called the Cabela's Ultimate Alaknak™ Tent – 13' x 27'. How are these in wind and weather? I think these are nylon insted of canvas. Are there advantages or disadvantages to each. Thanks for your insight
