I have a 454 hauling a 22ft class a motor home. Engine cooling is fine, new coil, cap and rotor, need to change the plugs. I am averaging about 5mpg which seems a bit low. Can anyone out there with a similar set up let me know what you are averaging.
The last trip was hilly, that probably made a difference.
Thanks
