Heres 3 that ive made. First one was out of 2" channel (very easy build). Would be easy to tie into stock receiver to strengthen then add receiver to bumper. Bed and tailgate still very functional.
Next was my personal favorite. Off a squarebody S10. Took 4" out of center to avoid overhang at the ends. Again easy enough to strengthen enough for receiver or rear winch. Winch in pic was just mockup. Bed would not tilt with this. Took maybe 2 mins to remove though.
And lastly my tube bumper. Bed still tilted and tailgate lowered 90%.
All these used mount similar to EMP (rear rops factory mounts). But mine are alot stronger. 2" receiver welded to 1/4" flat that bolts between rear rops and frame mount.
