This should settle the "coil spring" question
I stumbled across a thread on one of the Cummins forums where several members posted pictures of their coil sprung Ram 2500s loaded with various weights. HERE IT IS

I'm not sure why there was ever concern. The RAWR of the 2500 is still less than the FAWR on a Ram 5500 (or Ford F550) which also uses coil springs. I've never seen a 550/5500 looking close to overloaded, even though builders are now putting 21' roll-back decks on them.
Even most rail-cars are coil-sprung now :)
