In a similar boat here. Had a set of KOs then KO2s on my '99 1500 and loved them. But haven't tried them on this heavier truck. And if they're getting complaints more recently maybe they changed something. Personally leaning towards the Nittos as I've been seeing a lot of positive commentary with them.
Based on comments just on the first page so far I'd say try out the Toyos if those are your preferred two. I hate to pass on the KO2s but I don't have experience with recent versions to counter other observations.
Edit: After the rest sounds like Nittos might not be 100% either, although still more positives than negatives. This is why tire choices suck. Everyone has different experiences and they seem to work differently for everyone.
