I know this isn’t super cheap for a 5lb propane tank, but it’s a popular one and very well reviewed. Comes with a nice custom travel case and adaptor hose to use with 1lb connections. It would be ideal to use with portable grills like the Weber Traveler. The little green bottles cost $4-5 each, and these tanks are 5x the size, but only cost ~$3 to refill (or so I’m told). Seem’s most UHaul locations to propane refills, in case you are wondering where to get it refilled. (You may also be able to find an adaptor online to refill it from a standard 20lb tank https://store.nashfuel.com/products...r-hose-kit-system-fill-bbq-20lb-unloading-lpg)
