We got our topper yesterday - a Century / Leer ... we have 1/8" to spare on a standard door opening.
I can trim off about 1/4" on the flexible trim seal of the door opening. So, the clearance will then be 3/8"
Be sure that you get one that fits 2022 SD ... I am sending mine back to Amazon.
It is about 1/4" to large in both dimensions ... might fit if you remove the bezel to install?
With the aid of a level and laser ... the back of the bed on an F350 is 1 1/4 inches higher than the front of the bed.
Some garage door openings will NOT accommodate the height.
