If he meant that he should have worded it that way. He insinuated that all dually have heavier suspension than all srw trucks. Which is wrong. Also there are lots of srw 400s that have the same leaf packs as the duallys. Either way no matter how many leaves you have it doesn't negate the many advantages of bags. Especially when speaking of trucks such as the gmt400 as there are many non duallys 20 years later rated to haul much more.I would assume he meant specifically within the gmt400 platform, as there are plenty of newer srw trucks with heavier rear suspensions than these duallys.
