One of the issues I have with the LGMax is the small box in front which contains the single propane canister and battery. On long camping trips, certainly a second bottle is required. Storing a second bottle somewhere while traveling is somewhat inconvenient along with carrying a second backup battery (easily put in the see through storage area). Has anyone built or purchased or modified a box for holding two propane bottles? Looking for ideas before going to a trailer store and cutting up a new one. Thank you.
