My idea was something similar but with a round pole. Hoping I'd be able to swing the crane boom from left to center to right. You know the C20 that has that stop a freight train GitRDone bumper on it? I wanted to use the reciver and 2 brackets on the bumper to put angled supports and make a removable swining boom. I can't set **** down in my backyard cuz it's all grass and the hoist just sinks. Having a swinging boom hoist, I can just back the truck up and set engines and axles down where ever I can back the truck up. As is now, it has to sit in the middle if of the yard and not up aginst a fence or in a corner. I have to lift with the hoist, drive out from udner it, set it down, and that's where it stays.
