Got some interesting information on the frame while having my fifth wheel installed.
I asked why they went to a boxed frame when the older frame was so strong. The shop owner reported that they have seen several Generation Two trucks with cracks in the frame near the junction of the cab and bed. He thinks that frame strength was one reason that we didn't get a crew cab sooner. The frame wouldn't take the extra stress.
He speculated that the guys with broken frames were probably way over GVWR causing the frame to crack over time, but he thinks that the new frame will prove to be stronger.
As far as hitch installation is concerned they bolted the hitch supports to the side of the frame rail. One existing hole was able to be used, and three new ones had to be drilled on each frame rail. The key is they only drilled through one wall, not through both sides. Then using a snake they fished the bolts through access holes about two feet further back on the frame and attached the nut on the outside of the frame rail. He says strength is not compromised, and no problem squishing the frame since it does not go through both sides.
Anyway, like everything they do it looks extra strong.
Interesting about the cracks in the Gen. two frames though.
