I just thought of this yesterday and figured I'd throw it out for comments.
Lets pretend we're on a mountain road and maybe throw a trailer into the mix. There is a long down-grade followed by an uphill grade about the same length and percentage of grade coming up like a roller coaster ride. To get the most out of your fuel do you:
a) Coast down the hill saving there and power back up until cresting the next one.
b) Power down the hill (and maybe exceed the posted limit slightly
) using momentum to help climb the next hill. Less fuel used going down due to gravity assisting might fall into play.
c) Steady speed along the entire grade and hills but needing to power up the next hill from a nomimal speed at the bottom.
I know that in my situation with a fairly heavy (11,000 lb) 5th wheel trailer and our PSD powered truck it hates being pulled down in RPM on a hill. Loosing speed absolutly kills it on a hill. Is there a simple answer to this question? I'm looking forward to what PSIG has to say on this one as I respect his opinion greatly. Thanks all!
