i bought a wall tent from davis tent and awning in denver. 12x14 with internal frame, screen door and a window. i checked around and asked everybody i could. i even puta thread on here and everybody had great info but davis had only good reviews.
i just got back from a 9 day elk hunt with 3 guys and had room to spare. i got the tent on a monthly special the put on their website for $600 and that included shipping the window and screen door. then i bought the angles from the army surplus store and the poles from home depot and cut them myself for less than $200. it was still a lot of money but i will say probably one of the best $800 investments i have ever made.
