Bakflip MX4 issue

Recommended Posts

Just installed the MX4 tonneau cover today on my 2020 GMC 2500 with the 6.9" bed. Only weird part is when I try and fold the cover forward it doesn't rest against the cab like it should:

They did send two different sets of bumpers and I would assume I need to use the thicker rectangular ones but they still aren't thick enough to get the cover to rest against the cab

Can anyone with this cover tell me if there's rests against the cab?

 

Thanks

I have the similar Undercover Ultra Flex and mine doesn't rest against the cab.  Why do you want it to rest against the cab?  Surely, you won't be driving with it in this position.  I've only driven my truck with the cover fully open one time and I used the support arms to hold it into place.   Doesn't your Bakflip MX4 have these support arms?

I looked at the photos of the MX4 here  https://bakflip.com/p/bakflip-mx4-tonneau-cover/  and I believe it's because the beds of our trucks are 6' 8".   I could be wrong but the cover will probably only rest against the cab if the bed is the shorter 5' 8" in the half tons.

I'm sorry.  I was wrong.  I went out and opened my cover and it will rest on the back of the cab.  However, I've never allowed it to do that.  I simply have always used the support arms on both the right and left to secure the cover in the fully opened position.

Mine will touch the cab if I force it to. I can then lock it there with the arms.  I normally dont got that far with it, I just make sure it isnt blocking the camera and call it good.

It does block my camera when I open it up completely.  But I've only done it once, so no big deal.

I'm not planning on driving like this often, but if I need to I was just worried about it "flapping" back and forth. It does have those rods but there's still some motion in it since I can't snug it against the cab.

I drove from Ohio to Florida with it an 1" or so off the cab without any issues.

@GearHead71, I'd be interested to see what the bed view camera and the rear view mirror look like from inside when you have the MX4 up like that. That's the bed cover I'm looking to get as well and haven't found any pics of the cover up like that. Any chance you'd be willing to either let me know whether or not those cameras are blocked or post a couple pics of the camera views with that up?

 

Thanks,

 

Alan

If you force it to the cab and then crank down the holders, it’ll stay against the cab. It also won’t obstruct the view of the review and bed view camera. I specifically choose this cover for that reason. Moving from a bumper pull to a fifth wheel and wanted to be able to have the cover out of the way and hitch up. It’s also convenient when filling the bed with stuff to have almost full access to the entire bed space. My old truck and cover took up half a foot or so of bed space fully folded up, which only mattered when I had bikes in the back. That half foot meant I couldn’t close the tailgate. Not an issue on the longer standard bed of this gen truck though and this style cover.

I'll take a picture when I get home. Not sure it will be much help since mine doesn't fold all the way to the cab yet though.

Even if I push on it I can't force it to the cab. It starts to bend up the small panel at the bottom. There's only those two bolts holding it to the side rails.

I think this is the problem. Here is a picture of my truck, see how the top of the cover slants away from the cab:

Here's my buddy's truck. See how the top of the cover slants towards the cab:

Basically, mine is binding up on itself while his still has room to fold forward and rest against the cab.
