Earlier model truck has a single larger 12V 120amp 1000cca battery, just a better setup.
Jap trucks above, my KW uses 2 12V 1100cca Delkor in series 24v start 12v run.

What sucks about that setup is if one battery is cactus or on its way it pulls the other one down as well, with our customers we'd fit 2x NS70X which is a higher capacity variant if there was a lack of room or convert to 2x N70ZZ if we had the room and could hang the batteries out of the holder a little further.
There was only about $5 difference in margin between the smaller NS70 and the bigger N70ZZ, so mostly we retrofitted the bigger ones in.
Bigger is always better
