sean i have a few wall tents mine are from yakima tent. i wouls say go no smaller than 14x16 cause evan with only two guys with all gear room fills up fast no matter how organized u are.as far as options go i have a zippered screen door in front along with the regular door makes for nice in warmer weather keeping the bugs out. also zippered windows in the side wall are great. stove hole out the roof dont like much the ones out the door have seen some tents catch fire from that style.i also had frames made for mine for times when not packing in anywhere makes for quick set up i can have my tent set up in about 5 minutes with one guy helping tad longer by myself. hope this helps.
