I tried the 2 setting on a trip and saw no difference in fuel usage and prefer the Mode setting so I hit the Mode button before I put it in drive every time now. I read somewhere that you might be able to set the default to mode so it is that way when you start up but havent researched that yet.
I would think the normal shift (not MODE) would give better MPG on the flat just because it has the engine turning less RPM till you get to 6th. At first I did not think MODE allowed you to get to 6th, but then on longer flats I saw it does. I like how it down shifts sooner on interstate hills so you only loose a couple MPH before the shift. In non MODE it was maybe double and then it had a hard time not loosing more. With MODE my RV is almost fast (for a RV)> In 2005 I bought a 45 ft Navigator with a 600 HP Detroit, that RV was almost fast and it never lost speed anywhere.
I bet Verona which must weight only a little more than my coach but has the bigger engine 1100 lbs of torque is just about right on power. Same for Dynamax as they offer the bigger motor too, but at a big kick in price.
