We are leaving soon to go out west to Yellowstone and other areas…love our Rockwood A-frame. So much fun when we went to the southwest in 2017. The one thing we’ve noticed this year is that when one gas tank is empty, it doesn’t automatically switch to the other tank. We have to switch the tanks around as when either tank is on one certain side, it won’t work. We figure a blockage of some sort…anybody else ever have this happen? Thanks friends!
