As far as I know, there is only one aftermarket manufacturer of Vanagon gas
tanks, so likely it will be the same.

We do ship to PO boxes, but the gas tanks are just a tad over the post
office's maximum size, so they can't go to a PO box; this forces us to use
UPS or FedEx (who cannot ship to a PO box). We do require that your FIRST
order be shipped to an address that is tied to the credit card you are using
(whether that be a physical address, or in the case of a slightly smaller
item, a PO box if you prefer). However it is easy to tie your physical
address to your credit card. With the exception of debit cards (which can
vary in policy), all you have to do is call your credit card issuer (at the
number on the back of the card) and ask them to add that address as a
"secondary" or "shipping" address. That can be your home address, your work
address, your mechanic's address, or wherever you want; you can remove the
address by simply calling them again. Then, when we charge your order, we
get an approval code that indicates that the address is legitimately tied to
you. (It does not actually show the address; just that it is legitimate.)
This is done for your protection, to ensure that nobody has hacked or stolen
your credit card number and is using it to mail-order merchandise for
themselves.  Any retailer who does not take this security precaution (which
MasterCard and Visa strongly recommend) is not doing you any favors, as they
are not protecting you from credit card fraud. After your first order, we
consider you an established customer and do not insist on this validation.
