Update... My only question right now has to do with the necessity of keeping Tow/Haul mode constantly engaged. CA put a sticker on the gear shift that urged keeping it in this mode for better fuel economy. But I find that the gears are not shifting smoothly and race the engine to 4,000 RPMs plus before finally changing. That can't be good, especially when just starting out and the engine / transmission fluid are cold. Today, I finally disengaged the feature and it runs so much more smoothly...and much lower rpms. Appreciate any wisdom shared here.
Lotsa opinions on this one... I run with it on especially when in the many hills and mountains I travel here in NorCal. Sometimes leave it off in the flat valley areas... but normally on. The Ford V10 is a screamer and high revs are not a problem beyond your ears :-) The switch just changes shift points for max power sooner (climbing) and engine compression braking sooner (downhill). Comfort is sacrificed for better performance... if you think about it compared to an empty van you are always towing/hauling all that RV mounted on the frame. Keep reading on it, do what feels good but I will tell you that you should ABSOLUTELY have it on for extended downhill runs... overheated brakes are a bummer.
