I hear you about the tire. One of my goals is after a long day of wheeling is to be able to park, crawl into the back and go to sleep. maybe stretch a tent over the rear end at most. I want to avoid the set up and tear down of camp every night. In addition I have a large 3500 watt inverter, two 300AH batteries, air compressor, tools, and spare parts box to go into the back on both sides under and above shelves yet to be installed. There is not a lot of room left inside for anything but me. On the other hand to put it on the rear outside I would have my rear view blocked mostly by the tire or have it hang down to low and catch on things (been there before). besides I made myself a promise this time I would have my winch stuff (D hooks, snatch blocks, remote, gloves etc.) in ammo boxes under the headlights near the winch and tow gear ( Straps, tree saver, cables, chains, etc.) in ammo boxes on the rear gate. I want to avoid crawling around inside of the back gathering my gear while precariously hanging on the edge of a cliff or about to roll down a steep stump filled clear cut. Those things need to be at the ready incase of emergency. In addition its nice to be able to swing out my rear gates and drop my tailgate and shelves and slide out my stove, BBQ, water can, and kitchen box onto the shelves and again not to have to lift anything but still be ready for camp in a second. When I finish the exocage I have a slide mount designed for the tire that will pull out over the side and hinge down to rest against the side of the cage and put the tire at waist height for easy removal. That might work for 40's but they are dang heavy, I would need help I think.
