Exactly. Twelve refills to break even is not bad. Right now, getting refills might be the inconvenience- I'm guessing the equipment to refill them is proprietary, so you have to find a U-Haul
If the idea catches on, price and convenience may improve as more vendors offer the service. I think the concept has merit. I just hate throwing away those canisters, and even where available, recycling is far less efficient than reusing.
I'm toying with swapping the single 5 gal. tank on my Scamp
for two 2.5 gal. tanks- one to fuel the trailer (stove and furnace
only, no fridge
, used infrequently) and one to fuel the camp kitchen (stove & lantern). I already have one from my tenting days- love the size, and plenty of capacity for our camping style. Might make the battery
box easier to access. Expensive, though, and no after-hours swaps at convenience stores... hmmm...
