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.
F350 ICONIC SILVER 4x4
CCSB Lariat 6.2 / 10spd
Picked up 10 days ago ... nice weather! Got the Lariat because we wanted Baja interior.
Waiting in the mud for rain to stop to install accessories ...
We'd rather see snow - especially our GSDs.
Early 2022 got an email for 3,000 to be used by 4/4.
Original order was 11/08 and we recently received another PCO via snail mail.
We used the $3,000 two weeks ago.
