I know that there's the economy of scale. More produced=cheaper per unit costs because of production costs.
That said, how different are the two? Are the gauges or guts 'that' expensive?
Same questions for smaller LP tanks? In my camper I have height limitations that I'd designing around so I want a cylinder that's shorter than the typical exchange-type cylinder. Whew...they're spendy too, for less iron???
All of that said...what vendor is a good source for cylinders, either new or used.
Thanks for any insights,
Tom
