How Thick is BAKFlip MX4 Hard Tonneau Cover # BAK48204 When Folded Up
Updated 12/08/2025 | Published 11/23/2025
Question:
2026 Ram 3500 8ft Dually How many inches does the front mounting area and the four pieces take from the bed when all flipped up against the back window? I have a below the bed rail tool box that will need to be mounted forward enough to allow me to pop the lid open. So how many inches of bed am I going to lose with this bed cover in order to pop it open with it all flipped up against the rear window?

He Joe, The BAKFlip MX4 Hard Tonneau Cover # BAK48204 is approximately 3" thick when folded onto the front panel up at the cab of the truck. The panels are 1/2" thick but they don't fold perfectly flat and there is some other material in there as well. If you count where the latches sit it is closer to 4-1/2". Will that work for you?
