I got rear ended by a rice burner one night in one of my Ferd rangers I used to own in the late 80's. I was at a stop sign, I looked in the mirror and watch her coming as she looked over her sholder getting ready to "merge" at a stop sign.
I had a trailer hitch on this ranger. She hit me so hard it lifted the back of the ranger up as she drove under it. The trailer hitch cut a nice hole through her hood, radiator and through her engine block! I drove home, she was tottled.
Next day I put the truck on a lift, and the frame bent right in front of where the trailer hitch mounts. The hitch has added strenth to the end of the frame, but allowed it to bend up in front of the hitch. Dealer wanted $4000. 00 to fix it. A torch, big pipe wrench and cheeter bar and it bent right back!
