Use a floor jack to hold the old receiver in place while removing the bolts and to lower. Also to raise the new one in place and hold while installing the new bolts. Last thing you want is to drop it on your head while trying to man handle it.
It took 20 minutes to swap mine out. A lot longer to install the new trailer plug receptacle into the bumper. The original plug recpt was attached to the OEM receiver and I saw the new trucks had them in the bumper. So I drilled, used an electrical knockout and filed to fit it in. Came out like a factory job.
