Its alright to put that much weight on the bars, a 3 car wedge trailer would be too much tho. Use 2x2 with a 1/4'' wall thickness, 3'' wide bushings instead of 2.5'' to spread the surface area of the load across the bolt, and make sure the axle tabs you use are 1/4'' thick (mine are). I wouldnt run an offset bag setup (what people commonly call behind axle) let alone tow with one. They put the weight of your vehicle on a point thats trying to rotate the axle thereby pulling one set of pars and compressing the other. Adding weight only makes the problem worse and will wear out bushings and even bow linkbar crossmembers. Mke sure you center the bag over the bar so it wont twist the bar leading to bushing wear. I would also never run any kind of reverse link setup as it is exactly that, reverse. It will actually want to unload the weight off the backend of the truck while braking instead of planting it, and youll be making the truck "drive" from the rear crossmember instead of in the middle of the truck where theres more weight and has a better center of gravity.
You can run a 2 link if you want but i would reccomend against it. With a little more time and effort youll have a setup youll be much happier with.
