Running the gererator while driving

We run our Onan while underway to make sure our rig is nice and cool upon arrival to our destination. It's your rig, use whatever amenities onboard as you see fit.

It is easy for the dash air to cool a 22 ft MH. Different story when the MH is 31ft or longer.

That's when most of us that have longer MH's use the gen to run the coach air. I have dogs in the coach are so I use the air.

Just a note when you have to drive during the hotter part of the day just put van windshield sun shades under the day night shades to keep the sun out while you are driving is to slip under the shades and are easily removed when you arrive at your destination. You will be amazed how this keeps the coach are cooler.

A must IMHO is putting RV vent pillows in all the roof vent openings. Keeps heat out and ac cool in. This alone will bring the temp down 20 degrees when driving in real hot weather conditions!!

Put these in your roof vents and sit back and feel the difference in summer AND winter. :C

We do it occasionally, especially if traveling in very hot weather. Sometimes the dash air is just not enough to keep it comfortable. Also, then when we stop for the evening, the air is already running while we are getting parked and set up, until we get shore power connected.

If you are driving into the sun, run the defroster to cool the windshield. The sun heats the windshield which then radiates heat back into the coach.

When we ordered our MH I specifically ordered it without engine air. We always ran the genny and roof air to cool. Worked fine for us. As a side benefit, less strain on the motor.

You shouldn't have to run the house A/C unless there is someone sitting in the back. Do you have a curtain between the driver cab an the house part?
