I think you are way overthinking that to an extreme. Heard of no issues with a fridge support being needed. All fridges are on an exterior wall which would hang outside frame. Many even in a slide out with less support. Rear mounted probably more supported than most since frame goes all the way to the rear.
Just my humble honest opinion.
