Another possibility is to use a single smaller propane tank. Say an 11# capacity fiber composite tank. They are pricey compared to steel but have a tare weight of 7.5 # compared to about 13# for a steel tank of the same size and an 18.5# tare weight for a 20# cylinder.
Fiber tanks are translucent so you can see the propane level in the tank, monitor the use and know when to refill. So they work well when you have a refill place reasonably close to home and can be backed up by an adapter to connect the 1.1# throwaway bottles to the camper, which will do for a day or two of non-furnace use.
