Good choice. I have one a year ago and it works well. Only one recommendation. Put it on a solid surface and preferably not very close to the walls or ceiling of the RTT.I got this Mr Buddy Heater to try it out. My sleeping bag is good to 15 degrees but when I poke my head out of the bag I can see my breath. My thoughts were if it was warm in the camper I can sit down and watch TV and not in the bag keeping warm. So I Got one. It works great. I have just a Snug Top Camper nothing big so I been using it in a small space. I turn it on just before getting in the camper to warm it up and I turn it off to sleep but in the morning I turn it on again to warm up the camper to get dress. I have not noticed any fumes of carbon monoxide, but did get a smell of the new burning off but after that it was good and it did warn you it that. The 1 pound propane bottle last about 3.5 hours on high and about 6 hours on low but the way I have been turning it on has lasted about 3 days per bottle. Cranking it up, uses it up. I found the Mr heater Buddy priced around $99.00 but I got this one at Walmart for $74.00 maybe that after winter sale. My dogs love it they found a new place to lay by, the heater. Any one using another type of heater for in the camper?View attachment 87463
