i picked up a pintle hitch trailer but wanted to be able to switch between the pintle and still have a receiver hitches. a few months back i had a welder cut off and replace the rear bumper with a 3" receiver. we had an engineer run numbers on it and it will be good for way more than the truck can tow. thought you guys might get a kick out of seeing it. in 1 of the pics i set a 2 1/2" ball itch on top to get a size reference.
