Q: Does your RV have multiple propane tanks?
Q: Does your regulator let you switch between them (manually) and might even let you sit it in the middle so it draws off of both tanks at the same time?
Q: Do you realize why that is a bad idea?
A: Drawing off both them at the same time is a bad idea, why? If you are drawing off of both, when they run out, you literally now are OUT OF PROPANE, there is NONE LEFT. Make the conscious choice to use one at a time, so you know when it is time to fill when one gets empty versus now you are completely out of propane. Be smart about propane usage.
