Under more normal conditions I get between 7.7 and 8.5mpg on a daily trip basis. Overall is 8.2 for the life of the coach *~71K miles according to the VMS. See bottom line "KNW"

I am very impressed with this screen, what a great tool.

The great thing about the Silver Leaf VMSpc is that each gauge is in a separate window which can be sized to your preference and moved to any place on the screen. You can choose from around 20 different gauges.

Second, it runs on any Windows laptop at least as far back as WIN98. I pulled my old WIN98 for the back of a closet and it's the one in the picture.

Third, the software is free! You just buy the special cable with appropriate serial or USB adadaptor and "decoder" for around $400. You can download the software and just play with it on your computer. I set up my basic configuration at home and the hace modified it several times in the coach to suit my idea of the best screen.

I just get a kick watching the Torque go from 150 ft/lbs while cruising to full bore when going up steep hills.

Here's the link to get the software:

Yes, I agree that would be fun to watch. I am not sure if this system is compatible in older coaches like mine, But I will definitely be looking into this one. Thanks.

Yea I just checked my mpg on this 4th of July trip to michigans upper peninsula. About 400 miles each way and only got 7.5 mpg but traffic moves about 75 to 80mph so I drove between 65 and 70. Towing a Jeep Wrangler. So don't want to know the difference as its just going to make it worse.. Had a great time so it was worth every penny. Just wish lake superior was warmer than 45 deg. It was painful getting in to swim but the whole family did.

Just retuned from Denver including Colorado Springs up to entry point at Pikes Peak. Avg mileage for round trip thru Raton Pass was 9.1 mpg so I am happy with that.

I've been following this thread with some interest despite the fact that I don't have a "Class A" anything.

WTTW:

My take is that folks' suspicion of your numbers is likely founded on their uneasy sneaking suspicion that they're fudging their own numbers, too...if only just a tad.

Just an opinion from someone outside, looking in...and rest assured that It's Never Been Smoked In, was Only Driven To Church On Sundays, and will Truly Respect You In The Morning.

It doesn't help a lot to post your mileage numbers if you don't post what kind of coach you're driving and what engine it has.

I averaged 10.0 MPG on the last 6000 miles from QC to AZ.
38' Scepter with a Cummins 330HP. I drove at 62-65MPH and the RPM was 1500.

On our current trip from Birmingham, AL to Orlando...
On the trip down, ScanGauge reported 9.5MPG on the mountainous terrain of I10 and I75 cruise set at 60MPH
On the return trip I set cruise at 65. On the same sections, SG reported 8.5MPG. These numbers are very consistent with previous trips.
Actual calculations based on fillups would be skewed because we ran the genset the whole trip due to a bad alternator. Genny usage is not accounted for by ScanGauge.
Motor is Cummins 330 ISC towing an Impala on a dolly.

I never use the Scangage...I do my own calculations based upon fuel used and miles driven. It's more accurate. When I do use the generator, I keep a record of how many hours I run it. I deduct 1/2 gallon (diesel) per hour. On my last trip across the country, I got exactly the same mileage going to South Carolina as I got on the trip home.

Ramzfan, I use both ScanGauge and keep detailed records. I don't have enough data yet to be confident of either data source but I have seen enough consistency to trust ScanGauge (to a degree).
The generator is the biggest unknown. My user manual says up to 1 gallon per hour on full load. I was running both A/Cs and refrigerator while travelling so half a gallon per hour may be about right.
On our first (900 mile) outing, I calculated 9MPG using just fuel fillups and cruising at 62MPH.
It seems my numbers are fairly consistent... 8.5 - 9.5MPG depending on my cruise speed. I have not had to do much mountain-climbing yet.
