Steven,

The person you talked wasn't very familiar with their past practices since
I'm fairly sure that the Manchester tank on the Adventurewagen is smaller.
It's classified as three gallons but with the safety valve holds about 2.8
gallons. The AW doesn't need as much propane as the Westfalia since its'
refrigerator runs on 12v (two 6-volt golf cart batteries).
