Can the cab be set on its back?

[MrDude_1]

This sounds like a dumb idea.. but maybe someone else has done it.
I have my cab on a dolly.. but its about 1' off the ground, and the dolly wood makes it hard to get under.
I need to blast the underside of my cab to prep it for a new floorpanel patch.. while im under there, i also want to brace the underside of the floor a bit more.. so i need to blast the whole underside.

if i carefully lifted it off the dolly, and set it down with the back of the cab on the ground (firewall pointed at the sky) on my lawn, would it damage the cab?

im thinking no.. but im not positive.
has anyone done this before? ive seen some pics of people having the cab sitting on the firewall, but thats where im working on it at the moment.

if i can do this, i'll put it there, blast where i need to, then weld it up like this.. and if i cant, i'll just tough it out. with the center plate removed, and the rusty panels chopped out, im sure i can reach under there to blast anyway.
