And a lot of hypermiling I bet.
Most of that is too extreme for my taste.
ON a van I need my side mirrors, I live in AZ so keeping a block warm is almost unneeded and as this is treated as a RV only gets driven every once in a while.
You hypermilers should look into the old Borg Warner Overdrives, they had a feature called free wheeling, it was a one way sprang that with out power to lock it up allow the engine to drop to idle, and just a little push on the gas and it would spin up and lock.
On these old overdrives a pull or push of the control cable would either free it up to free wheel or to lock up and give engine braking.
Years ago I planed on using the whole transmission, without first gear, but using the 3rd and 2nd gears as a under drive, with 3 at 1:1 being no under drive and 2nd as a under drive...with these transmissions you can engage or disengage the OD as it is its own transmissionat will so I could split all gears...
SO I would have a 8 speed with a 2 speed rear end. OR another way to look at it a 16 gear system. 8 low and 8 high.
I still have two of the OLD Borg Warner 3 speeds with OD in storage.
BUT building a shifter and mounting it the floor and the cable control and then adding a modern VSS sensor kind makes it a bit much, and adding that old cast iron tranny is another pain. AND a weight cost as well.
On the other hand converting the OD to a stand alone system has some merit.
