Is this an automatic propane switch over valve?????

We have a 2012 Chaparral with what we think is a auto switch over valve for the propane tanks. We do not have any instructions and are not sure how this animal works. The valve has both a red and green dot and what looks like an amber site glass in the center. Looks like the one in the attachment. How does this thingy work????????

Looks like the one on my 2014 lite so I will say yes it is.

Turn on both tanks and fire up a stove burner or the furnace to get gas flowing then turn one tank off.

Yup. I had to figure it out, too:

the one with the green dot is the draw tank turn that one on first if has gas the center dot should turn green then turn on the other tank. When the center dot turns yellow the first tank is empty turn the green dot tank indicator to the other tank and the center dot should turn green you can then disconnect the empty tank and get it filled.

From experience, I'd recommend leaving one off,,,,,when you run out,,,,just go switch them,,,,,then you know when the first one went empty and you can get it filled before the second one surprises you and goes empty also. I found out the hard way on a cold winter night that I had already automatically switched over and the second one went dry at 3 A.M. at 26 degrees outside and 58 inside. .... It's just easier to know exactly when the first bottle goes empty so you can stay on top of it.

Grandpa Jim is right on. Been there too, easier to switch and relight than freeze. The refrigerator and hot water need gas when boon docking.
