LOL, do you know anything about hydroforming? There is not ONE hole drilled into the frame, they were hydroformed. A hydroformed frame is like spring steel and will crack if drilled too close to a bend or too close to another hole.
Hydroforming is a process...basically they took a piece of mild steel pipe and made it an oval...that's a lot of high tech there.
The Dodge Builder's Guide indicates the frame can be drilled and welded as long as it doesn't happen at a radius. The hydroformed frames are NOT heat treated, they are mild steel, just like the old "C"-channel frames. I have drilled holes all through my super low tech hydroformed frame...it hasn't cracked in 138k...I also haul a slide in camper all over the place, and again, not a single crack.
You should also crawl under your truck and look at the frame, as it is full of punched and drilled holes...the frames are also welded (full radius of the frame) since they use a single front section with multiple rear sections for the multiple configuration (long bed standard cab, shortbed quad cab, long bed quad cab, etc).
I have talked at length with the regional Dodge rep about this because of this paranoia (I was under the same impression as you at one point due to misinformation on the net) and the fact I wanted to drill the frame for a hitch. He put me in touch with a group that handled body modifications for different applications...they set me straight.
And again, with the exception of being thinner, there is actually very little difference between the new frame and the old ones.
