Ozarak Farmer - the stove you're looking at is a good one, I use it in a tent out moose hunting. Sometimes to get the proper draw, it may require more stove pipe than what you want to put up.
For your purposes in an RV, you should use a Toyo stove. Some require electricity (12V ?) if you want to set a thermostat and others don't. Instead of a pipe up through the roof, you put one pipe out the side which brings in the fresh combustion air and sends out the exhaust. They're very economical and safe to run.
