MX4 tonneau question......fifth wheel hitch

[Bombdigitty]

Getting ready to order a tonneau for The new truck. 2021 2500 CCSB
interested in the mx4 cover and I want to get the back box as well.

will the cover interfere with the fifth wheel pin box when folded up flat. (Not talking about flat against the window.

how thick is the stack of panels above the bed rails?

currently I have a 1500 with same 6’4” bed and an extang soft trifold. It works fine folded up.

Got my answer on another forum. Should work for those wondering.

Thank you for that information. I wondered the same at point as I am ordering a Bak F1 cover, and maybe the box too.

Im sure the mx4 will fit but sceptical about the f1 cover. It is 3 panels instead of 4 so will come back further when folded than the mx4
