Another thought for the airbags is to use something kind-of like what U-Joint does for their vans, with no fixed lower mount ... allows the axle to articulate past the bag extension, if you have that much travel. Winds up being a similar concept to like a hydro-bump or something (probably not news to you, but here's a good illustration of hydro bumps upping load carrying in a Raptor application: http://www.rpgoffroad.com/a-performance-and-towing-suspension/), but probably quite a bit cheaper (also not really any added damping).
Part #ABZ01, about 3/4 of the way down, on this page: http://www.ujointoffroad.com/4wdparts.html ... obviously this isn't a drop-in, but rather an illustration of a concept that I'm sure you'd have no trouble with implementing for the Ute's specs.
I was pretty sure I had said it before, but if not I'll say it again: that modular concept for the bed/load-out is really appealing; as an engineer, multi-use stuff is always intriguing to me.
