Getting ready to buy first tent and am torn between the Mini Wall and the Monster Wedge models. It would normally just be me using it but my wife may decide to join me (at least once). I know I would loose a little floor space with the mini wall. But I was thinking I could get a cot close to the wall and with the wedge the cot would be have to be set away from the side by at least a foot and I would loose that space for storage anyway. Has anyone used the mini wall? How would you compare a wall to a wedge?
