I was in a 05 KW that was perfect for the job.
With only 260,000 original miles its only issue was CARB related.
As for the batteries in the cab?
I think it's a heat issue and the limited or lack of space.
I don't think the batteries in that space are such a terrible idea, since all that ever gets put there is junk and water from the floorboards gets in there and rusts said junk anyway. What I do think is bad is the fact that 4 bolts and the whole seat have to come out of there to get at them. There should be some kind of a quicker way to get in there. But it probably would be better to put them in between the frame if possible for the type of truck.
