Looking for sources/ideas for various portable heaters (for winter camping). Temperatures down to as low as -25C.
I'm aware of Planar diesel heaters, as well as the endless Chinese clones. Also aware of Propex kits from Adventure Trailers in the US. I'm not looking to spend what these options are asking for.
Specifically interested in dry-air heat (ie. no Propane Buddy heaters), or other methods of keeping comfortably warm.
Are there other ready-to-go options that I'm missing which would be suitable for a tailer-mounted RTT? Tent is a FreeSpirit Recreation M60 Adventure Series. I'm aware of FSR's insulated Tri-Layer fabric option, but it's fairly expensive and tough to justify for two-three winter camping trips per year.
Current plan is to install some of the pink home insulation panels on both the interior of the RTT (I figure I get away with 1/2"-1" of insulation there) and on the bottom (1" will be an easy fit). This should give me around R7-R9 of insulation, depending on the products used. I'll also remove the current tent mattress, and replace it with the (slightly smaller) Exped Megamat Duo LW (which I already have); that's another R9 worth of insulation. Then I'll get sleeping bags rated to -30C, and leave the current 100%-down comforter on top. That should provide & retain plenty of warmth in the sleeping bags, but it would be great to have some warm air around the bags, too.
Any cost-effective ideas?
