And yes, people try to improve their fuel economy on motor homes all the time. Yes, there is always some improvement to be had. The fuel $ savings on big rigs is substantial, since they consume so much fuel.
Going from 10 mpg to 12 mpg is a 20% improvement and will save you 20% on fuel, which would be significant if you drive a lot.
The biggest improvement you will see in a driving a big giant brick is to reduce speed. There is probably a 20% increase in mpg in slowing down to 55 mph from 65 mph.
If your car is newer than 1996, get yourself a Scan Gauge II or other real time mpg monitoring device. Changing your driving habits by watching the gauge can save you another 20%.

Sorry I thought I had included those specifics.
We own a 2007 E350 Superduty , 12 passenger auto 2wd with the 5.4L with OD.
We had the plugs all replaced, within the last 10k. Coils were tested individually and all are working as they should be ( per Ford ). Air filter was replaced just 6 months ago ( approx 5k ago ).
Going to change the oil in the next few days.
I'm just now starting to track my mileage after joining this site , so I can obtain some idea of where we are at .
