For various reasons, I decided not to install the trick horizontal propane tank I'd gotten for my trailer under the tub. After selling it for the same amount I bought it (whew, dodged a bullet there...), I'm back to square one. I've pretty much decided on carrying propane bottles instead, but I can't seem to find a good variety of small bottles (specifically, I'm looking for 5lb bottles that taper down at the bottom like regular propane bottles *see left on the attached picture*, the only ones I can find locally go straight down to a lip on the bottom, and those don't work for my mounting method). Can anyone point me in the right direction? If I can find the right size, I might carry two of them, for now I'm looking to carry only one. Thoughts? Suggestions? Flames?
