They have no floor and they do have a hole (stove jack) for the exhaust pipe from a wood burning stove.
Maybe they have changed but ours has a floor as well as a floor liner including a zip out section where the wood stove goes.
A plus over a canvas tent (and I considered both) is the Alanak is much lighter and requires less storage space and requires less care than any canvas tent I found.
In KY during deer season we often have mid-day temps in the 60's and it's nice to be able to open both ends plus the windows if you're looking to take a midday nap out of the sun. With the OP in AL that might be a factor.
Of course, YMMV depending on climate and other factors but writing it off in general seems to be shortsighted.
