Advise please!--To remove cab or not?

[72step]

I am going to be starting some cab rust repair this coming weekend and I've been pondering removing the cab. Ideally the easiest access would be to rest the cab on it's back to deal with replacing the outer sections of cab supports; however someone on another forum said it's not a good idea because the cab wasn't made to rest on it's back and you can cause it to shift. The cab is actually pretty solid. The only rust it has is the driver rocker and cab corner and the very outer few inches of the cab supports. What would be the best thing to do to deal with this? I keep thinking that with the time involved removing and re-installing the cab I can pretty much finish the required work. I'm thinking if I lift the truck pretty high one side at a time it won't be too bad. It's literally the cab supports within the closest 2 inches from the inner rocker on those way low points of the cab supports. Thanks for any advice!
