i built one a couple years ago, for the same price..actually cheaper..i can get a fiber glass one with grey carpet and quiet slide plexiglass...real nice too...if ya shop hard you can find em for $700 + the legs
, but i will build my own deck to put it on..so basically $1150 seems like alot, til you build one..spend the same thing ya would tryin to get one up 12'-20' ..mine is about 15 feet+/-...square tubing frame ...heavy gauge for safety.
put the front 2 legs on...tie it to the truck and pull it up while 2 other guys put the legs in the back side in the slots and set it back down....and a steel frame will last...even if we ever have ta rebuild the blind.
i would recomend a deck outside the door for xtra safety..i just have a ladder..a good thing is with the steel just right..i can insert smaller square tubing into the existing and add a porch..just aint done it yet.
just remember..there is never enough time to do it right the 1st time, but there is always time to re-do it again later!!
