MY QUESTION:  How many pounds/ liters /gallons does the standard vanagon
LP tank hold.

MY SITUATION:  Last year I bought a 5 lb (about 1 gallon) tank for $29.
It was a $ based decision and it works great.   I have to run the hose
out the drivers side sliding window for my heater.  I need a vent
anyway!!
I need a bigger tank and am thinking again about getting the real thing.

Thanks,

Mark
