[PSUBS-MAILIST] Pro's & Con's of Propane Tanks

[DSmith4038@aol.com]

          I would be interested in gathering some pointers on using old 
propane tanks for a pressure hull. For instance , are the old propane tanks 
that were used on delivery trucks thicker walled than the old stationary 
residential tanks? Should I shop for one of them? You do see a lot of these 
trucks around so they must become surplus at one time. I would like a large 
tank, maybe a 1000 gals or better for my psub. So guys, what are some pro's & 
con's on these propane tanks ?? Also are there other types of surplus tanks 
better suited for psubs?
