Added gas line for cooking outside of TV

Follow up: Anyone know the pressure of the low pressure lines in the TM? I found out that portable grills, like the Coleman, want 15 PSI on the line. Is the TM's copper line anything near that, or is it down in the 2 range like Coleman seems to think?

Standard pressure in most low-pressure propane installations is described as "eleven-inch water column". These words are used in the TM refrigerator manual, for example. In other words, the gas pressure is sufficient to support a column of water not quite a foot high. Since water has a pressure of about 1/2 pound per vertical foot, that is the value I would expect to find - not 15 psi, not 2 psi, but about 1/2 psi.

FWIW, I run my portable Coleman propane stove by running a hose between the stove and the propane cylinder, no pressure regulator.

Let me rephrase that. No additional pressure regulator. My Coleman stove has its own pressure regulator, to deal with the pressure in the little bottles. When using a larger propane cylinder, there is no reason to use an additional regulator.

My Coleman stove runs from the little green/blue bottles. My propane cylinder is a similar pressure. There is no reason for me to be using a regulator to reduce the pressure.

This is why I did not tap into the gas line on the TM. If you want to do that then you need to do so at the cylinders, before the pressure regulator.

That has been my experience.
