In preparation for my Slee rear bumper without a tire carrier, I crawled under the 100 this week end to look at the current spare mount. I was looking at what it would take to get the spare higher up under the 100. There are three areas that need to be addressed. The first area is the front rail that pushes against the tire. It is mounted to the cross member in front of the spare tire. This was simple. I unbolted it and flipped it over and bolted it back on. It didn’t really matter much though as the tire rests against the cross member now and doesn’t hit the rail. The cross member is smooth so I don’t expect it to damage the spare any more than the rail would.
