The weld nuts on your vehicle will likely have to be cleaned out. Over time the threads can get packed with gunk and make it seem like the bolts are too large when really they are not. Use a spray lubricant such as PB Blaster and soak the weld nuts.

Let them sit for about 15 minutes and then scrub them out with a brush such as # 814092 or a battery terminal cleaner such as # DW00254. You may have to do this a few times depending on how gunked up the threads are. I have included a couple of links that will help.

You will have to go with a sliding hitch to allow the trailer to make tight turns. For a trailer 8 feet wide the only bed length that's going to allow 90 degree turns without a slider is a stationary hitch. That being said you have two options.…

Hey Jerry, GM moved the placement of their puck systems starting with 2020 models so you are correct that the pucks would have the hitch not sit directly over the axle. GM did the math and made sure that this placement wouldn't adversely affect…
