Thats what we do. Will set the Propane furnace to kick in if the inside temp drops below 35-40 degrees or so.
Then we run a couple of the oil-filled portable low profile heaters plugged into the 20AMP service at the pedestal using an extension cord running into the trailer.
Using the 20AMP Service does not interfere with the 30A or 50A service you have the trailer plugged into.
We hate the loud BRRR noise the propane heater blower makes and hate to burn up all of my propane. Our oil-filled heaters only go CLICK ever now and then... The oil-filled heaters also do not give off burnt dust smell or have a visible red hot core or flame to deal with. If we need to move some air around we will use the O2OOL 10-inch AC/DC/D-CELL fans sitting behind the heater.
Its better for us to use the camp ground electric then our propane hehe...
