Tonneau Cover Help

DeadManWalkin · August 15, 2020

So I just bought a 2020 GMC Sierra 3500 AT4 that is replacing my 2012 GMC 2500 GFX. The new truck was bought to pull a 5th wheel. I want a hard folding tonneau cover for the truck. I am between the GMC REV industries cover ($1100) at the dealer or the Bak Industries MX4 ($1400). Does anyone have any pics and input on these 2 covers. I know the MX4 will allow the bed camera to still be used. Does the GMC one allow this as well? Ive heard Rev is just a private branded Bak cover that manufactures rebrand for sale at dealerships. Pics of the new truck and camper and a side by side with my old truck.

Have you checked out the Undercover Armor Flex folding cover? I purchased and installed one a month ago. I previously had an Undercover Ultra Flex on my 1500 and it worked great. The new Armor Flex works even better. Almost zero water in bed. The linex coating looks great as well.

No I haven't but will look into it thanks.

Just looked at it but don't like how the cover blocks the camera on the 3rd brake light when folded up

I have the hard folding rev/bak cover and its not a perfect fit...its good quality otherwise but either my dealer messed it up or they havent adjusted well to the bigger beds. It hasnt bugged me enough to send it back, but I do need to plug holes for water intrusion

Where is the water getting in. I'm thinking around the tail gate for sure. That multipro is probably going to be had to get a seal around

Just got my BakFlip MX4 yesterday for my new 2500. I bought mine from AutoAnything. If you call them on the phone and tell them you're a forum member here, they will knock some money off. I paid $917.72 shipped to my door

Its the corners closest to the back of the cab. Huge gaping holes that are not sealed by weatherstripping. The tailgate seems fine to be honest, especially after i bought the stake covers

Just finished installing my BakFlip MX4 and I have zero large gaps. Now i'm not claiming its gonna be water tight and I don't need it or expect it to be. As long as the stuff in the bed is semi-secure and not getting directly rained on, i'm good with it.
