Good advice. While camping in June, I noticed the changeover valve was showing red for the RH tank, so I switched over to the LH tank. When I got home I took the tanks off the tongue & got them refilled. I could hear sloshing in the RH tank & the LH tank seemed noticebly heavier.
When I got them filled @ a local truck stop (there's always a person or 2 getting tanks filled), the attendant asked why I was getting them filled as they didn't really take much propane to fill. I said, I wasn't sure about how full they were before I left for camping (trailer had sat on lot for a year & I had been trying out the various systems) & didn't know how much was left.
When I got home, both 20 pound bottles weighed 36 pounds on a digital scale. I guess I'll just have to weigh them to make sure.
About the changeover valve. Is the red indication quite distinct or is it faint? I may have seen a red reflection thru the glass & thought it was red & ready to change. Instructions for the valve are a poor translation from Chinese to English.
