Thank you everyone ❤️ I shut off all power to the RV, turned the propane tank electric switch off, turned the manual knob off, then turned off the supply line to the stove that was under the fridge. Turned on all batteries and 50 amp, turned on electric tank switch and slowly opened manual knob. Checked to make sure fridge worked with LP then opened stove supply line and turned on stove. Ta Dah.
