With this propane idea it brings up more thoughts on the dual use of the inside of the frame tubes for containment of a gas or air. If your frame is air tight and you can pressurize that badboy with a compressor to maybe a few hundred PSI, with a regulator, coil hose, and tire filler and valve adaptor you could have a mobile filling station for your raft/cat tubes and/or vehicle tires. Never mind the fact that if lose this air seal the few hundred PSI could blow a hole in your boat, blow you off the boat, or cause your raft to take off to space potentially let alone the fact that you will crap your drysuit from the ensuing bang scaring every animal for 20 miles. I mean I got tears streaming down my face just thinking about the possibilities LOL!!!!
