The problem I have with a camper or camp trailer is that you can only go where you can get the camper. This is one of the biggest advantages of tent camping. Most of us endeavor to get away from the crowds, get away from other hunters, other camps. At least here in the mountain areas that often means that you can access more remote areas if you can get into areas on old unmaintained roads which are often too rutted out for campers or camp trailers to use. We've always seen this as a big advantage. If even one member of a hunting party is using a camper, and you want to camp together, then you're limited to areas that camper or trailer can access.
The Mr. Buddy heaters are a fantastic option for many situations. But, be aware that for every pound of propane burned, you're putting a pound of water vapor into your tent. In cold weather this can become a real problem. That water vapor quickly cools once it contacts the wall of the tent and turns right back into water. You are probably also hanging wet clothes to dry, maybe boiling water for coffee, exhaling, etc. too, all of which add more and more moisture to the inside of the tent. Add a little wind and it will literally rain on you inside the tent. Particularly in single wall nylon tipi's or other coated nylon tents this condensation issue is a constant problem. Dry radiant heat from a wood stove is a far better option if you can make it work for you. Canvas tents with wood stoves have long been the best option for cold weather camping for these reasons.
Disclaimer - Mansfield Outdoors is the sponsor of this forum and we sell high-end lightweight Tentipi canvas Nordic tipi tents as well as nylon tipi's, wood stoves, etc. But, I got involved in importing and distributing the Tentipi brand from Sweden because I became a big fan of them first, and knew they would be a very attractive option for many North American hunters.
