BAL Tire Carrier Install on narrow frame

This is an install video explaining how I modified the BAL 28218 to fit my 2022 Winnebago Micro Minnie 2306bhs. This tire carrier is meant for full width (8ft wide) RVs, so I had to do some big changes to get it to fit.

What is width of the area you had to modify to fit? I have 40" to span and wondered if this cut be cut down to fit.
