I respectfully suggest that before spending out on a large and expensive stove, you acquaint yourselves with the beautiful, small, American made Fatsco Stoves!
The high quality, cast iron and stainless steel Pet Stove and Tiny Tot Stove are charcoal/wood burner's used in ice fishing shacks, cabins, live aboard boats, travel vans, etc, for about a century.
I spent six months researching to find a high quality charcoal/wood stove to fit into a small travel van without being too large for the space and consequently being too hot.
The hugely favorable comments from the wooden boat forums, bus and travel van owner's (and the fact that I loved the stove on first sight) led me to buy a Fatsco Pet Stove last year.
These stoves are miniature marvel's, and you can also buy a dual cook top (as well as every single component of each stove as spare parts) should you wish to. They are also remarkably inexpensive (even when shipped to the UK) and the owners of Fatsco were great to deal with, lovely people.
Google Fatsco Pet Stove and Fatsco Tiny Tot Stove and see for yourselves...
