No gas thruout the trailer? Not even the stove? You have a blockage at the supply tanks, possibly the auto changeover valve. They do go bad.
Your fridge does not work on gas, either? Obviously, double-check that you aren't low on propane in both tanks. Get the supply verified, check that the changeover valve is operational. Propane flows like water--from origin to use points--need to figure out where it is being blocked, or if it is even coming out of the tanks.
