Tire mount

I have a situation where I had to remove the spare tire mount off the back of my trailmanor so it would fit in my garage. I dont want to be forced to go through the unbolting of the whole mount everytime I put it in my garage. Has anyone been faced with the same situation? I am thinking of having a receiver mount welded to the underside of the bumper and somehouw have a removable tire mount that could simply slide out of it. The mount would need to be flush with the bumper to not add any extra length to the camper. Any thoughts?
