+1 on a Mr Heater Buddy or Big Buddy. Yes they do produce a fair amount of moisture but they ARE rated for indoor use. The Big Buddy also has an onboard fan utilized with D batteries or a 6vdc adapter and both of these have "tip over" shut offs. I used a Buddy heater for several years in a 15' travel trailer and also in a pop up and the smaller one was more than adequate.
I agree with Saddlesore, a wood stove will be too much.
