Around us, many of the U-Haul truck rental places sell propane (not an
exchange; they fill your tank). It's metered (sold per pound or
gallon; I can't remember), so you don't lose out if the tank isn't
empty. The total price for a full tank is generally less than any
exchange price I've seen.

In my very urban part of Silicon Valley, everyone uses natural gas for
heating (and hot water) and I've never seen a house that uses propane
for anything. Yet within 1/2 mile there is a gasoline station with
propane, and several more places within a few miles. We're not a big RV
area either.
