We had similar problems with our 2010 Mountaineer Onan generator. I talked with the engineers who manufacturer the regulator and was surprised to find out that the regulator is designed to use both tanks when running the generator. There is also check valves in the connection lines which can be a problem when installing refilled tanks. Follow the procedures outlined in the owners manual when installing refilled tanks. When I understood how the system worked, and made sure there was propane in both tanks, my problems disappeared. We boon docked at a NP in Yosemite last May at 10,000 ft and 21 degree nights. We ran the generator 6-7 hours a day between am & pm, and each day I refilled both tanks. You don't want to know what I was paying for propane!!!!
