Propane question
My fifth wheel has two tanks like most, if I put the knob in the middle and not right or left will it choose the full tank when the other goes empty?

One caveat- the changeover works on pressure, if it is very cold, the regulator will draw from both cylinders.
Interesting...any rough idea, as to temp, when this will happen?

It’s hard to determine- it has to do with temperature, level of liquid lp, and draw on the cylinder. When the level of liquid gets low enough, it cannot absorb enough heat from the air to vaporize the liquid fast enough, and if the cylinder pressure drops below ~20 psi, the reserve cylinder will start feeding as well.
The good part, the furnace and all appliances will keep working, which they might not on a single cylinder, the bad, you can, in the most extreme cases, run both cylinders empty at the same time.
