While its not a big expense to run the genset, about 1/2 gal. / hr. as mentioned earlier, but from a cooling point of view it's definitely not the best choice.

Regardless, if the genset & rooftop unit keeps the drive quieter, doing it is probably the better part of valour!

Think the consensus was to slow down a bit. And if I have passengers/ie...whiners running the AC will cost ya an extra 0.5 gal/h = well spent.

I can live with 6-7 mpg especially if pulling something. My real hope is that I can travel more than 300ish miles before having to stop an fill up. With a 55 gallon tank, I was hoping to get some more road under my feet before stopping.

Just a quick update - Came back from the beach...ran about 62 tops; pretty much baby'd it back Seemed that I my fuel consumption based on the gauges was less aggressive. I had a 1/2 tank left. Started with 2/3rds. I didn't run the generator on the back either. I know it doesn't use much fuel in comparison but just wanted to see the difference.

So any ways, I went and filled up - 28.8 gallons which is about 1/2 tank as advertised. Total of 176.5 miles. The math says 6.13 mpg....that was about my guestimate.

I suspect knowing what I know now, I will get it to improve a bit.

It takes many thousands of miles before you get an accurate "reading". We have almost 40,000 miles on our rig and it's still not enough according to Cummins and their tests.

My V10 is a couple years old now and mpg is still improving (10K miles) 98% of the time I am either pulling the TOAD or the boat. last check was 8.2 and i am happy.

How fast do you pull? This is good to hear that it gets better with time.

Short 70 mile trip is not much to figure MPG.
Take a 300 mile or longer trip. Than check MPG average.
Maybe your driving the MH like a car. With a heavy foot.

As has been said, slower speed, and letting engine break-in will all help. Towing a car will save more fuel than running it separately in most cases. Wind can also be a big factor. Most tuners will maybe help with power, but power costs fuel. Seldom do people see much improvement in fuel economy with a tuner kit, especially when you factor in installation expense. At 6 mpg you've got over 300 miles between fill ups. At 60 mph that's 5 hours of driving. I'd hope you stop more frequently than that with those 4 and 6 year olds. There's lots to see and explore along the way!

Keep a log of miles driven and total gallons used. you can figure it every-time you fill and it will vary greatly, depending how level the gas station apron and how level the coach sets. After a couple thousand miles your total miles driven by total gallons used is going to be a good measure of your actual MPG. If your not in the 7's get your foot out of it, don't drive with cruise, so you can feather it and stay out of "kick down" to lower gears, or as us old guys call it "passing gear".
