Third the opinion of not bothering with hydrogen. The short of it is that producing hydrogen is a lossy process. You have to burn more gasoline to make the hydrogen, and the energy you get out of feeding that hydrogen back into the engine doesn't make up for the extra fuel needed. Plus to make any significant amount (not just a fraction of a percent) you'd need a monstrous alternator.

Making the hydrogen with grid power, pressurizing it and storing it in tanks which you then load into the truck are more likely to have close to zero return, rather than a large negative return.

Depending on the drive cycle, a plug in hybrid conversion could have merit. I have tons of ideas on how to do this, but most won't be cheap.
