I'm using a Garmin EcoRouteHD which reads the fuel flow data from the engine's OBDC port. From that data, we're averaging just about 10MPG with our 28Z (which is actually 29ft-10") on a E450 chassis.
One thing with the EcoRoute - I can watch how varying the speed by a few MPH affects the fuel mileage.
I usually drive between 55~60mph on the interstate.....

I'm curious - where do you see the peak in MPG?
like if you were to plot an Z-Y graph, MPG vs MPH (or MPG vs RPM)
assuming flat ground, no wind, and steady speed.....
Is it 55-60MPH or is that just your best compromise between speed and efficiency?
I have been wanting to get an OBD reader just to see where it is with my coach. I know it will likely be a bit different since our weight is different, and maybe even our gearing and such...(?)
When I first got my silverado with its built in read out of average MPG, I plotted this. I expected the peak to be maybe 30-40MPH, but was surprised that the peak was right around 55MPH
