I put battery heaters standing vertically in both the battery compartment and the basement.
Pictures show the difference in heat going below running the furnace and using electric heaters only. The basement is usually 5°F warmer than the battery compartment. The underbelly sensor is in the void space under the island. Remove the panel under the sink covering the plumbing and you will find a BIG gap going all the way down to the underbelly.
We recently purchased a small 350W ceramic heater. Works great in our S&B bedroom. Planning on using it in our Montana bedroom. It would be perfect for the basement OR underneath if you have a skirted RV.

Ensure it has good clearance at the back for unrestricted airflow.
