^ And while I believe that whole heartedly (I'm hauling an Arctic fox on an older Ram 2500), the newer coil spring 2500s are an inherently poor design for high center of gravity loads. Haven't used one, but reports are they are less resistant to body roll than leafs and it makes sense.
However, if I had that truck, airbags and the biggest sway bar I could find and I'd try it.
If someone makes stiffer coils IMO that would be preferable, but not sire I've seen any.
But with a Cirrus 720, it might handle it pretty darn good, especially if the truck is a long bed.
I'd go for it and not worry.
