If you're going to do this, a nice extra step would be a Zodi propane fired hot shower. They usually have some on Ebay (http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=1856600738).

Also if you go to their website, they even have one where the heater coil sits on your 2 burner stove

More expensive but worth it if you hate cold showers.
Also at Cabelas ...
