It depends on what your needs are. I have a Yeti and a Pelican as well as everyday coolers. When you need to keep stuff cold for multiple days the Yeti or Pellican cant be beat. Example, i filled our small Yeti with frozen meat one morning and took it to our son, it was the next afternoon before we got there and it was still frozen. We also go on multiple day trips in our RZR and the coolers keep our food and drink cold the duration of the trip.
I have 2 - 2015 2500 series 4wd pickups similarly equipped in front of my house. Ram with 6.4 has 3066 payload and Chevy 6.0 has 2882 payload. That said buy what you feel fits you best as they are all capable trucks.
