Getting the spare tire out....

I had an enclosed hitch cargo box custom built for my 2016 GMC/ 10.4 Bigfoot camper. It has drop down doors on each side.I had the fabrication shop drill a 1" holes in the box in line with crank tube on my rear bumper so I can open the cargo box door, pop out the plastic plugs I have inserted in the holes, use a stiff wire with small hook bent into the end to catch hold of the tube hatch and pull it open, insert crank rod and use a ratchet inside cargo box to drop tire. I remove the lock cylinder from crank tube before I put hitch cargo box on. I set this up and did a dry run with it and it worked fine before i left home.....low & behold if I didn't have 2 flat tires in Arizona this spring due faulty valve stems ( GM warranty issue) and had to use my spare tire both times. First was a front tire so was able to lift truck ok with camper on. Second was passenger side inside dually. I lifted the camper up off the truck bed about 6 " to relieve weight then jacked truck up and changed tire no problem. Its a time consuming proceedure but it all worked good. I put the spare back under the truck by myself both times too using the ratchet to winch it up. It was a bit awkward getting winch wire thingy thru the wheel hole while working under the camper overhang and cargo box. Hopefully I will never have another flat again, but I am prepared if i do!!
