I recently built this one for some private land that I hunt with my daughter and wife. That is why it is so big but you could build one 4X4 and it might better suit your needs for less money. I started with 4X4 posts and just framed the whole thing on the posts and then the posts were used as legs....
This is a pic of it with the windows installed and set up on the ranch
