That cooler is rated for 30000 GVW. That should do for what ever you decide to haul. If you don't haul anything the cooler tranny temps will make it last a lot longer. I see they include ties for strapping it to the radiator. I like to mount mine separatly with the cooler in front of the rad but not touching. Remember the flow goes through the cooler and then back to the tranny.
