I'm not sure what you're getting at. My scenario is extremely simple with no added variables. When towing, the 5.0 will not keep up with a 3.5 in the hills. It's not even close but no, the 3.5 won't match the mileage of the 5.0 either no matter if they keep their foot out of it or not because when towing, the 3.5 is always in boost. The 5.0 just doesn't have to worry about that. This scenario only applies when towing. If not, and especially on the flats, the 3.5 will get better highway mileage. If the 5.0 has a 3.31 rear and the 3.5 has a 3.73, I think the 3.5 will still get marginally better on the highway (while not towing and otherwise empty with all other things being equal). If you're fighting a hurricane force wind out of Florida, I won't make an assumption either way.So...if the 3.5s just slow down and hang with you their mileage might improve to match yours?
Is the 5.0 not capable of keeping up?
The scenario you're describing would apply to identically powered and configured vehicles wouldn't it if one truck raced up the hills?
