Harry,
What you see is correct! The reason they are on the outside versis
the inside, on the outside if there's a leak, nothing happens other than
you smelling the gas telling you you have a problem that you needs to
fixed. If this happened with the gas lines inside, you don't smell the gas,
the gas builds up in the underbelly a spark happens and BOOM!!!
We get to see you at the Big Airstream Rally in the sky! And there's
not even any good parts left to sell on Ebay!
