Rod,
Thanks for taking the time to share your experiences and observations from the maiden voyage. As a new owner that drove a new-to-me coach home to Baltimore from Phoenix last December, I was very interested in your story. I averaged 8.5 MPG on my 2300 mile trip (1976 23' with 455 and OEM Rochester Quadrajet carburetor) and am most curious about your engine, final drive and fuel delivery setup. Regarding the the gas over-fill experiences, I resorted to extremely slow fill-ups. I never came close to even the first detente setting on the fill nozzle. Even so, I recall having about a 1/2 quart of gasoline over-fill/spillage at several fueling stops. Like you, I have read much about vapor lock and several other hot-button topics, but am now curious whether your and my tank filling experiences are typical and how to avoid them. I took to estimating gas needed based on miles driven and stopped filling 5 gal or so before I anticipated full tanks. Based on your experiences, I'm also making a mental note to check that I have a full compliment of on-board spare belts. Save travels.
