looks like from the picturs that the batteries have to be replaced and or serviced from the top meaning the cab and bed would have to be removed !
Battery comes out through the bottom. There are a couple of steel plates to remove, then some bolts in the inside the cab that need removed. Lower vehicle onto battery service table just so they touch. Remove bolts from bottom and raise vehicle body back up. Couple of connectors and coolant hoses attached to battery need removed. Before hand also. Then with battery out you can remove a top cover to access the battery modules.
