I do have the mopar skids, I will have help but whats so special about the skid?
Well I have a buddy and an impact wrench and have experience taking out the back body panels, it isn't hard at all so I can handle that.
There is nothing special about the skid. It is a pain in the butt trying to hold up the tank skid and the trailer hitch by yourself while you are trying to thread in a bolt before the whole mess falls on top of you.
I did it by myself. I took out all of the bolts except the two bolts at the rear of the Jeep, I just loosened them off so the tank skid did not come off the Jeep. I then put the front two bolts on the hitch and through the skid plate into the holes in the frame. Once I got the first one in, it was fairly easy to get the rest in. When I got to the front, I just took out the two bolts I left in, put them through the hitch and the skid and started tightening.
One suggestion, it is better to put on the wiring harness first and then the hitch. Once the hitch is on, it is really tight in there and you may have to loosen everything off to get some space to clip in the harness.
Oh yes, if this is a factory installed tank skid plate, the bolt under the tailpipe is a real pain. You will need a ratcheting gearwrench. Nothing else will fit in there unless you take off the tailpipe. You can use an open ended wrench, but pack a lunch, you will be there for some time getting it off and then putting it back on. The bolt size is going to be 18mm.
