This is something I haven't really heard discussed. When I've towed with our hybrid truck it always seems to drive way more smooth after having towed. My guess is the extra power captured from the trailer weight really packs the hybrid battery to full.
It could be completely due to the battery being 10 years old with 170k miles on it, and being nimh chemistry.... but it is a noticeable difference in driving characteristics after towing.
I would think that the battery being able to accept at least 270kw and the motor being able to generate 400+kw, mountain decent will be much more controllable that with a diesel truck.
