I was considering welding not to the sheet metal on the bed, but on the metal cross members that go width wise across the bottom of the bed. Upon research this doesn't sound like a popular idea. I've heard different ways of doing so. One is to mount straight to the frame, which is strongest, but I've heard this may lead to fatigue on both roll bar and frame and also inhibits articulation by limiting frame bending (not permemant bending, but natural).


Toyota frames are fairly stiff, I would not worry about the increased frame rigidity affecting articulation. Less frame flex is actually a good thing. There is no problem with mounting to the frame either, although it does make the cage much more permanent and difficult to mount.

The other idea I've heard is that a good bar mount is on top of the body mounts. This directs any weight (upon flip) to the frame, but isn't bolted directly to it, reducing fatigue and allowing minor sliping, sliding, movement between the bar and frame.


I think that this is a good option. If you don't like where the body mounts are you could even add this kit from MORE. I have an All-Pro interior cage and it mounts over the cab mounts, however it does take up a significant amount of interior space. I figured it was a small price to pay for safety.
