Propane and Propane Accessories

Can you elaborate, I don't understand. It seems to me that at higher altitudes, the pressure is lower so liquid propane would boil at a lower temperatures, producing higher pressure for the same temperature?
Since it's typically colder at higher altitudes, I can see where the cold at higher altitudes would effect the performance of propane negatively, but not the altitude by itself.

Less oxygen results in less burn?

I just remember the BTU/pound charts for propane in my backpacking books always de-rated propane at higher altitudes.

Although upright on top of the vehicle, might the 12 foot hose allow enough time at low temperatures for the vapor to condense back to a liquid? At that point it's running downhill again...

Highly unlikely, since propane condenses at -44 degrees F.

Good bit of info; thanks.
I've never seen it dip below zero around here.... ...thankfully...

Absolutely correct. However -44 is the temperature at which the liquid propane boils. What this causes is for the liquid propane to biol, generating (transforming) into vapor and thus causing the equalization of pressure within the container. It actually has very little to do with ambient air temperature. If the cylinders are not stored in an upright position liquid will enter the line and totally block the outlet. Generally you can tell if you are overreaching the capacity of the system when you see ice forming on the outside of the regulator and/or the cylinder itself.

The OPD valves will not cause an issue. Their design is such that they work very much like a float in a toilet bowl to stop the liquid from entering the cylinder after it reaches a specific point. What can happen though, all valves have an integrated excess flow valve built in. When you open a line into a new system (or a depressurized system) you need to do it slowly so that the excess flow will not slug shut.
