The better way to gusset it would be to move the gussets to the outside part of the frame, and run the gussets the full length of the tab (from the bumper to past where it bolts to the frame. That way, the entire tab will be strong in all 3 dimensions from the point it bolts to the frame all the way to the D ring.

I'll bet I could bend it. Picking up the truck is basically no weight at all compared to pulling on the bumper at a 45 degree (or more) pull during a recovery situation. You are puitting the plate in a perfect shear mode at the end of the frame. Think of how they bend metal in a press, you have the same set-up at the end of the frame. Move your gussets to the outside of the mounting tabs so they go all the way from the bumper to where the bolts go through the frame.

Trailer hitches are tube, or atleast angle iron where they mount to the frame. You are using flat stock steel. Competely different.
