If you trick the system so the computer thinks you are at idle but
your engine is turning 3000 RPM then won't you be really lean on your
fuel/air mixture?  Also if you have fuel firing in the cylinders won't
you lose a lot of the engine braking anyway?  So you might as well be
coasting?

If the grade is too long to coast safely with just brakes, I guess you
have to just be cold until you get to the bottom.  Turn the heat off
and close the valves the interior will probably stay warmer with no
heat than with a fan blowing cold air.

If you could rig some kind of a PTO to drive a generator, you could
feed a big space heater then you could turn that on and let the load
slow the vehicle *and* keep the interior warm.  LOL.
