He was correct -- partially. In fact they're called DOT cylinders because they have to be registered by the Department Of Transportation. BUT, so do the BBQ cylinders. If you look at the collar you'll see a DOT registration # on it.
Just for extra clarification, the permanently mounted tanks in motorhomes are not DOT registered but are ACME certified. You can find a U1 data plate on them.
a good place to buy cylinders.
