When you are moving and the dashboard heat is on, the flow of air into the MH can force heated air to exit. If your dash heater controls allow it, try setting the air to "recirculate" which seals off outside air and see if there is any improvement. Also, look for any sealing problems around doors, windows, and slide-outs.
You can also check the output temperature of your house heater when still and when moving to make sure that it remains strong while in motion.
