Skip Gundlach brought forth on stone tablets:
Some of you may be aware of, or, perhaps, already own (in which
case this may not be of interest to you at this time!) composite
Propane tanks. Briefly put (and follow some of the links I put
next if you don't already know about them), composite tanks won't
rust, won't corrode, are lighter than aluminum and way lighter
than steel. Minor size and capacity differences exist between
composite and steel or aluminum tanks, but are minimal in most
cases. They're taller by a bit, so if clearance is an issue for
your application, they might not work. Do a google on fiberglass
or composite tanks for an education - I think you'll be as taken
with this technology as I am. Also have a look at these links:

Here's just a few sources and prices, most of which are for the
"Lite" brand, and the 10 and 20# sizes...

Now, on to my story:

I had to get a replacement for my old-style valve on my 10#
aluminum tank. I brought it with me when we came ashore for
family stuff.

Fortunately for me, I was directed to Blossman Gas in Clayton,
GA, where it was accomplished in short order, inexpensively ($25
all-in) and refilled.

However, on the way in I'd noticed one of the composite tanks
sitting at the entrance door, and pointed it out to Lydia.

So, I casually inquired as to how much they were. $65!!
Needless to say (well, maybe not needless, but in any event) I
took one, filled. The circumference at its widest part is 3/4"
less than a steel tank, so it will drop right in where my barbie
tank is now.

Significant differences between it and a steel or alumiumum tank
are that it's slightly taller in the collar, and that it doesn't
have a tiny ring bottom, but, instead, is functionally flat.
That flat also results in its not being "rounded" at the botttom
of it, in the event, such as we, for our barbie mount, your
receiver is shaped like the ball-shaped base of most tanks. In
our case, it will just result in its sitting higher, which is of
no concern. It's a Ragasco, in the event that you feel the Lite
brand is critical to what I'm about to say:

Conversation with the manager, Sanford Thompson, revealed that
they had not had any success in moving them. That's cuz, of
course, they're more expensive than steel tanks, and most
landlubbers have no interest in tanks which won't rust,
particularly in this exchange-a-cylinder refill market, at about
double the cost of a steel spare/replacement.

When the comment about their lack of success, and the likelihood
of other branches being in the same non-boat, came up, I
immediately thought of this list, and other sailors, too, of
course (I'll be publicizing this on all the mailing lists and
forums I annoy).

So, they have, and can lead you to other branches in the event
the supply is gone after the word is out to the cruising
community, 17# (the nominal 20# size) Ragasco tanks available,
while they last, at $65 plus shipping, which they think would be
~10 or less. FWIW, it's quite lighter than my 10# aluminum tank,
even with both filled!

I have no financial interest in this - just an excitement at
being able to find a tank at a price I'm willing to pay when I
already have a sufficiency of aluminum tanks. The technology
really tickles my fancy. That I'm able to pass along a deal is
small payment for the learning I've received here :{))

How well do they hold up to UV?
