Storing Pop-Up TC in garage - Sloped driveway

My driveway is sloped towards the house and the one time I lost control of my popup camper when pushing it into the garage, it took out a chunk of the garage door frame. I now have a Yale electric pallet mover that I picked up for cheap.
Drop the camper onto a big pallet and use the pallet mover to move it to where I want. Unfortunately I don't have a camper right now but I am looking for another one so I don't have any pictures to post.
