I am sure someone knows the answer to this, cuz I cant find it anywhere. All my camping equipment that is powered by Propane (stove, lantern, etc.) all use the 16oz squatty fat tanks. I just received a portable propane BBQ Grill to complete my collection, and it uses the long skinny 14 oz. that most often are used to power torches and the like. Why are there 2 different types/sizes and what determines which one is used for what??? Thank you in advance for helping me free a section of brain to use for more productive figgerin!!
