I do not currently own an airstream, although I am actively looking. My brother owns a SOB MH. He told me there is an additive that is put into LPG in the north so that it doesn't freeze... As in, don't buy southern LPG as it will cause a freeze up in the winter in the north. Is he pulling my leg, or is he a victim of a running pratical joke....

proliner,
The 'additive' to which you refer might be the ethyl mercaptan, which gives the LPG it's distinctive odor. Otherwise, it has no smell to warn you of a leak!
Pure LPG is often 'blended' with butane with the blend varying by geographic location and the seasons. Butane is cheaper than LPG, which is why it's used as a blending agent, but it freezes at 32* F, so you have to watch out when filling tanks in a warm (read South) location and then traveling to the cold, cold North! I get calls on this problem every winter when the Snowbirds go home early and lose the use of their LP appliances due to the large amount of butane used in FL.

So - do you have to make fuel/air mixture adjustments between the two fuels, or does the temperature handle that...provided you purchase it in the proper climate?
I hope my question is clear

As a resident of the "cold,cold North" it's best to burn off your tanks by mid-Fall during bird hunting / leaf-peeping season and refill with some fresh, Northern-blended fuel. I fell prey to this problem on the way to Louisiana last year during a cold snap in Tennessee. It disappeared when I got to Mississippi...
No adjustment is required - just avoid the issue by having your tanks filled in autumn. The biggest part of the problem is when tanks are low and the humidity level is high just at or near the freezing point of water. To make sure I have "fresh" fuel, I use a gas thief arrangement to provide gas for a lantern and my BBQ. Even with 30 pound tanks, it is easy enough to use up the "old" gas over the summer.

I don't think ethyl mercaptan is added to LPG. Ethyl mercaptan is a whole lot nastier smelling than the leaking LPG I've smelled. It is added to natural gas for leak detection purposes though.
I've used propane down to about -10 without trouble, but it can get cold enough that the pure propane with no butane at all can still gel up. It doesn't have to freeze, it just has to get cold enough that it will liquify without any compression at all.

NOPE!
No adjustments are necessary to your air/fuel mix to accomodate alternative LP blends.
Glad I'm in the Pac NW now, where LP is $2.49-2.79 a gallon and I need a double tank fill.
What's with FL anyway? Diesel was consistently $.40-.50/ga,llon above premium. Here in OR, it's between a dime and a quarter more.

Hi, according to the link 2air posted, [post #5] "A powerful odorant, Ethanethiol" is used for propane.
