Headers can give some improvement to MPG. However since most RVs get less than 10 MPG an 10% increase would only be 1 MPG. If you are in the 7 MPG range a 20% increase would be 1.4 MPG which would put you at 8.4 MPG. Driving habits can make that much of an improvement. So keep expectations in line with reality. I put banks on my old ford 460 and saw about a 0.5 mpg increase but the power difference on hills was significant about a 10 MPH increase on Tiger Mnt in WA. My newer (2005) workhorse 8.1 already had the banks kit on it when I purchased it so I am unable to compare before and after.
