Hey Marlin,
Great news you can stitch your own canvas hot tent, that's what I did for about the third the price.  Internal "A" frame using extending paint poles made of fiberglass as well for the ridge pole too. Used 36"10oz sun forged fire rated canvas material, mine is 12'x12' and also has an 18" short wall that are easy to pull out.  The tent wieghs 36#'s, minus poles, snow stakes, stove and stove pipe, ground clothe and other misc. Using an uphostry sawing machine it took about some 10-12 hours to complete. I have not been disapointed since.

let me know if you hve any question?
