Here is a pic of an M725 on the assembly line without the ambulance alterations on it yet...the lack of a windshield or the mounts for one, no doors or bed...heck no back wall on the cab...sure looks like that is what this is:
As has been noted, the frame, suspension, drivetrain and the body stuff you see in the above pic are the same from the M715 to the M725. Whats missing in the above pic is whats different.
Lord send your Holy Ghost into our hearts and make the desire of our hearts Your Will.
Pro-choice, that's a LIE, babies don't choose to die!!
