My 3120 has 7/8" lug nuts. I bought a "new takeout" jack assembly, jack handle, lug wrench, and instructions for the E450. I'm not sure but I believe Ford supplies or used to provide them with the chassis. The instructions say how to use the jack on an E450 and since the only E450 Ford makes is for Motorhomes, I assume the jack is removed by the RV manufacturer. I was told by one RV manufacturer that they remove them because they don't want owners to change tires on a 14K lb vehicle for safety reasons. This is probably why you can find "new takeouts" easily online.
Yes removing the spare tire as originally installed is a pain. Pretty much need a floor jack to lower it or unbolt it, lower it to your chest and slide it out. I adapted a spare tire cable winch from a pickup truck so it can be cranked down with my jack handle.
Most people just pay to have a road service contract and just call somebody if they get a flat.
