it looks like the low Cd of the Tundra at 0.38
has got the other automakers thinking

Just like the 2nd Gen Dodge Ram of 1994-2001
whose design team called it the T300,
the pickup makers ought to be able to steal aero ideas
from the new Kenworth T660 and similar eighteen wheelers

To me the easiest
'low hanging fruit' to grab
is to do away with outside rear view mirrors
and substitute video cameras with thin & sleek mounts
at the outside corner of the front fenders.
Roughly this would improve MPG by 1 at 70 mph.

The GM Avalanche and Honda Ridgeline have shown
that if you add a triangular piece to the corner where
the rear of the cab and cargo box side meet
you get a reduction in the low pressure area that forms
behind the rear window and reduce aero drag
