As other have replied you can add another tank on the passenger side or now
there are replacements that are larger.  It should be noted that the small
tank was not just a cost decision. There are considerations with propane
capacity to the size of the dwelling and there are some limitations once you
go over 10 pounds. From my experience many of those limits have now become
no propane at all such as the tunnels around Maryland.
If going for the second tank do not just simply tee them together especially
after the regulators. They need to have check valves and teed on the high
side pressure side. There are really nice two tank regulators with automatic
cross over that can be used.   That is the best way to go.

Has anyone found a larger propane tank for the stock location? Or another
logical location to attach/carry additional propane without losing storage
space?
Thanks
