I just sold my 5th wheel. With diesel fuel topping $7/gallon here in California, I can't see pulling a trailer at 12mpg. So, the question I have is....what can of MPG can I expect to get from my 2000...
Won't be much better especially in the wind. I have been driving a Ford 7.3 diesel for the last 20 years. I added an AFE air cleaner, 4 inch exhaust and an SCT tuner. Best mpg is 23.8 mpg.
