Another vote for Davis Tent. We have a 10X12 with five-foot walls and it is adequate room or two with gear. For four people, you'd not regret going to 14X16 (or larger if you were going o have four in the tent often). We can cook and live in this space as well with a stove. This space is (again) adequate, especially if you use the disco cot bunk beds, which are now available at Costco. If you live in a state that allows you to do so, you may not want to order the fire-retardant treatment on the canvas. You, however, should consider the water and mildew treatment some companies (such as Davis) offer. I have screened windows on the sides and a back door as these options allow for great flexibility in ventilation, setup, etc. My tent is 15 years old and looks and functions as if it were new. That's because we care for it and especially dry it in a heated garage with a fan running for a few days after each use. I'm really happy with the angle kit I purchased from Davis at the time I bought the tent. I can set this tent up by myself (stove in and stovepipe up) in 30 minutes with ease. Pretty slick deal, for sure. Good luck with your search.
