Driving with the generator on
Just curious if anyone knows the difference in MPG when riding with and without the generator on. Has anyone done any measurements on the gas mileage they get? Thanks

Besides the greater fuel economy by NOT running the dash air you get the added savings on propane as your fridge will be running on electric.
So your rig engine temp will be less specially good thing on really hot days. Your engine a/c compressor will not be loading your rigs engine decreasing mileage.
Your fridge will not be using Propane.
Your microwave will be available for heating things
All in all I feel the economic part is close to a wash but the convenience and comfort level is much greater.
I'd like to see the science behind that idea.
A typical (large) automotive A/C compressor at maximum load uses about 4 or 5 horsepower. Now bear in mind that's ONLY when the compressor is cycling, which is FAR from being all the time.
If you look at the ratio of that load to what pushing the coach down the highway takes, I'd be surprised if you could even measure the loss.
There's lots of studies out there that show in a car or pickup, the increased wind resistance of having the windows open is actually greater than the loss by running the A/C
An idea or feeling does not necessarily have science behind it however I know I am damn comfortable doing it my way. If I want fuel economy I will buy a Prius not a motor home. So I stand by my statement that " All in all I feel the economic part is close to a wash but the convenience and comfort level is much greater."
