Heated mat?

Something like this: 110V, 730W, 5x2ft. Did anybody use it? When you have a grid power and morning temps inside are in mid 50s (12C). Near floor it's a few degrees cooler. Thick duvet keeps me toasty but need all my willpower to get out of the bed in the morning. It gets warmer when the sun goes up, but need to stand/walk for an hour while making breakfast. Small trailer, main habitat is the 6x2 ft "corridor" btw the table and kitchen counter, with a coach on one end and toilet on another. Looks like the place for a 5ft mat.

Or maybe put a space heater with fan, they usually have a power regulator: 750-1500W space heater. "Thermostat" is a BS, I suspect. At best it would measure the casing temperature and work on-off in either 750 or 1500W mode. Would love to have a real wall thermostat like in shore home.
