Grizzly metal works rear bumper mount up

[Hit it like a champ]

I was wandering how the rear bumper mounts up to a club car precedent. I plan on putting quite a bit of weight on this.a large Cooler and sometimes a generator. I was looking to build my own doesn’t look like there is much to hook on to plus the frame is aluminum I don’t want to bend that somehow. I have a ATV rack that fits into the receiver.
