In my TM, the block heater plug in is located in the compartment where the electrical shore cord/reel is located, L rear compartment. There is an electrical outlet, where the block heater cord plugs in.
My shore line is on a powered reel, with a switch, that powers in the electrical shore line.
This outlet is not on the inverter. (30 amps), thankfully.
