I'm a conservative driver and typically set the cruise at 62-65MPH and then just relax. My personal (20 year) experience with Class A MH is ~7.5MPG +/-1.5MPG variation caused by topography and wind. That's what it is for me and I'm good with it. The Five Star mapping does appear to have improved my gas mileage by ~0.5-0.75MPG; however, that's within the noise level of normal variation; so, who knows. I'm not aware of any product available that can truthfully promise significant improvement (outside the normal variation) especially for $500.00. I will say with the Five Star unit that our 36' Independence driveability is greatly improved as the transmission is less inclined to hunt and the engine spends much more of the day purring vs. roaring. Good Luck!
