One of the best things I’ve discovered is that most Tractor Supply locations sell propane by the gallon. This means, any time I am heading out for a weekend, and I notice the tank is getting a bit light, I will top off the tank so I don’t risk running out of propane. Bulk propane refilled in a 20 lb tank is affordable, and the tanks last for decade, so that means a lot of cooking, light, and heat up at camp without a lot of waste.
