Our M/H, an Itasca, has a system that uses engine heat to heat coach interior as warm as needed by anyone and also it heats the hot water tank. A very nice thing when arriving at a stop and needing to do handwashing, dishwashing, etc... and not wanting to wait on water heater !
The basement central heatpump will heat or cool the interior of the M/H, the same as in campground, and a lot more efficiently than running dash air at max and trying to zone off coach areas. At 50% load the genset burns a whopping .3 gallons of gas per hour. If I can't afford that the M/H will stay parked in the driveway !
Running the genset on the road offers other great advantages... microwave and coffee maker are just a few. I change oil and filter on the Onan every 150 hours for less than $25.00 and consider that an easy compensation for the convenience !
