Or an 18 with a 4...... had two trucks that way. Loved them. Stupid low hole and a nice lope down the highway at 70-75 gear as well. 8LL is nice until you get rolling then the gears get a little far apart ratio wise, same for a 15. 13's don't hold up to abuse as well. I will say I've never had a major failure from an 18 but they seem to get noisy, loose and somewhat finicky shifting after a couple hundred thousand hard miles.
