At the moment I am not in the market for one of these, but have seen Cushman's in action and was pretty impressed.
I am curious if anyone has tried to get a stove jack sewn into one? It seems like a good source of dry heat would be awesome come late season to dry boots and stuff.
Google will churn up a few threads/pics with a wood stove in one. On another forum, TxTrapper did one and posted pics there and elsewhere. His setup was pretty slick. He used a metal pan as a heatshield for the floor. Other pics I've seen recently used a nuway propane/vented stove in them. Looks pretty sweet.

I used a Springbar tent in MT many years ago for a deer hunt. I didn't have a stove, but a propane lantern warmed it nicely and fast!
If you can't tell, I'm researching heatable tent options.
