Mynewer Class C MH only has a 12 gallon propane tank compared to my 03 Minnie Winnie that had an 18 gallon tank. I am having to fill it much more often since tapping off it for my Little Red Campfire and Blackstone Griddle. I installed an Extend-a-Stay so I can either tap off or supplement the main 12 gallon tank. I'd rather use a separate tank for the Campfire and Blackstone and leave the main tank for the fridge and furnace. So my question is the storing of a larger 11 lb or 20 lb tank. Do you store it while traveling in an outside compartment and is it safe and legal? My outside compartments aren't really vented.
Carry upright in a compartment that is open to air either completely on one side or the bottom. (Compare to the inside construction of many travel trailers and fifth wheels that carry cylinders in on-board compartments.)
They need to be carried in an open environment. They have pressure relief valves that will go off should they become overheated. I have seen some tied to ladders in the back or on a carrier that is mounted on the hitch. My toad has a hitch and that is where I would put mine should I need an extra tank. Never in an enclosed storage .
