The Power Wagon is a 3/4 ton Ram with soft springs for articulation. Period. It IS an HD Ram. The 2500 and 3500 Ram share the same axles, frame (except for the parts necessary to change from coils to leafs on the rear), and everything else except for the actual springs. This isn't up for debate. There's no links to be shown. The 3500s sit about an inch high than the 2500s due to the actual springs used. Everything else is identical.
Where did you get the idea that a Power Wagon is a 1/2 ton truck because that is patently wrong?
I don't think he was referring to the PW as 1/2 ton; he was saying I compared a LC (1/2 ton), to a PW (3/4 ton).
And yes, to echo what you just said - all domestic 3/4 ton and 1 ton share the same frame, and in most cases axles as well.
I feel a lot of 3/4 tons have artificially low GVWRs limited only by suspension.
