For me what is missing today is any info that would lead one to believe that the truck mfg are looking at any form of a mild hybrid for 3/4 and 1 ton pickups. IMHO it's something that I'd go for in a heartbeat. If you could recover the energy from just stopping a large truck in city driving you'd see a big fuel economy gain, and If you could have a battery pack large enough to recover energy from a 1-2 mile 6% downgrade towing a trailer we'd see noticeable fuel economy gains when towing. And reduce load on the friction brakes as well.
Our Acura MDX mild hybrid, which will only go a few miles on it's battery, is good enough to boost city MPG from 16ish to a real world 26MPG for us.
