I have been getting hit about the old rear bumper a lot. Here is the deal. I charge $599 for these on the truck when they are new.
They are heavy duty 3/16" and YES, you can tow with it if you can put the bumper on yourself. I towed my pop up with it all over the place. You will need to be able to fab and weld to put it on though. This is a WELD ON bumper.
I will take $300 for it as it sits. No, you cannot run the spare in the stock location either. So, if you run it in the back or on the roof you will be fine.
It was built for clearance on a rock crawler so it fits tight to the body as it should.
