I've put some photos on my profile of my Frontier Stove fitted in my Belltent for Vivalebeaver to have a look at. Not sure how to send a message to you on this. I can measure the distance from the base of the stove to where it passes through the canvas if you are still thinking of buying one? Or for anyone else thinking about fitting one. We just went away to Comrie Croft last weekend and it was def needed as the evening were pretty chilly.
