Koen I have given a lot of thought to the short trip problem since moving back to the farm and electic with a wood powered generator is the best solution I have come up with. The biggest issue here for me is a lot of my driving is less then 1 mile and then the truck sits in the field while I load or unload at the barn with my tractor. Or all winter I move hay from one barn to another to feed my cows. So for me a short range system on electric makes since. I have even though about a small generator with charcoal in the bed so I could make longer trips if needed.
