We use these rubbermaid totes.
Have 1 for the hitch, and a second for the power cord and surge protector.
We keep them inside the rig during storage.
I can carry the hitch in the tote from the door of the airstream to the back of the truck, using two hands. I then set the tote onto the ground and lift the hitch into the receiver. This is much easier than carrying the hitch by hand the distance from the trailer to the back of the truck. Using the tote also keeps hitch grease from getting on the floor of the airstream.
If we take off the hitch while camped we put the tote on the floor of the backseat of the truck.
