tonneau covers that work with the multifunction tailgate?

[Rebel19]

Thanks to everyone in this thread for all of the great info! Ordered a right on bracket, the recessed screws from amazon, and a Bak Revolver X4s cover along with an Adarac Aluminum truck rack in black. Fingers crossed everything fits together and I'll be a happy camper. Will update with my results once everything comes in.

Hi, do you have a link to Amazon for the recessed screws? Thanks.

I haven't seen anyone talk about the Extang Trifecta ALX. Has anyone used one? I'm in a tossup with the ALX vs the Solid Fold 2.0

It'll install without modification on my '21 Big Horn (arriving this week) that does not have Ram Box but does have MFT. All the great info on this site says the brackets in the bed preclude most covers without using custom braces.

I realize it's just canvas, and I'm not 100% sold, but I think the WAF would be higher on that one do to the light weight and easy open latching system. Theoretically she will be driving the truck the most. And this is for protecting our stuff from the weather on long trips. I'm not really concerned about the lack of security.

Ok. This is my first post. But I want you guys to know that the Truxedo Sentry available for the multi-function tailgate. They have two version. I have the sentry and the also have the sentry CT. It is a hard roll-up cover. It is also low profile. They just finish designing the rails last week. I had to wait 3 weeks to get it, but it is better than expected. Had the Solid-Fold 2.0 and did not like. I have included some pics.

Looks great! Any leakage? I am not seeing it listed as being compatible with the MFT without Ram Boxes. Can I ask where you bought it? Thanks

I see it on the Truxedo site now.

Going to test leakage today. Will let you know.

I really liked the BAKFlip MX4 cover and was determined to make it work with my MFT. I had my own brackets made out of 3/8" steel from a local fab shop. After a few modifications, they are installed along with the MX4 cover. Only modification was small (1/4" x 3/4") trimming to the side rails around the two bolt holes where the MX4 mounting rail contacts the new L brackets. I feel it is every bit as strong if not stronger than the OEM bracket. Pic attached for reference.

Just finished installing a RetraxPro MX. Have to use the Right On brackets, they were a perfect fit. Install was very simple. Bought on TonneauFactoryOutlet. If you call or use chat they will give a good discount. It’s listed for 1829$, I got it for 1599$. No tax and free shipping. Also got a 100$ rebate from Retrax. Highly recommend the cover and the brackets!

Awesome! I did the same. Bought my Retrax Pro back when I had my 2019 and also got mine for $1600. Best cover on the market without question...just pricey, but you do get what you pay for.

I ended up slightly modifying my Under Armor Ultra Flex trifold to fit on my MFT 2021 RAM Limited. I do have some Right On brackets.

 

[danny6876]

I see it on the Truxedo site now.

Just wanted to update you. I went thru car wash yesterday. There was some leakage. About the same I received with my Ultra Flex. For me this was ok. Main point of leakage was on the front two corners. Main main reason for getting the cover was for security. I am one the believers that Ram designers made those brackets that big for a reason and I do not want to modify my truck. I also I tried the Solid Fold 2.0, but after one wash car the panels started to warp.

...I am one the believers that Ram designers made those brackets that big for a reason and I do not want to modify my truck...

You're correct, the RAM engineers made the brackets that big for a reason, although it might not be what you think.

When the MFT doors are open in the side configuration, they are basically huge levers that can apply considerable force to the frame of the pickup box. In normal operation, where just the weight of the doors is supported for a short time until closed, only nominal forces are applied to the frame. Over the life of the truck, this might stress the frame a bit, so the brackets can help with that.

But the real reason the brackets are there is in the event that undue weight is applied to the doors when they're open. For example, if someone heavy were to sit on the end of one of the doors when open, especially the longer one, the door would act as a large lever and the excess weight could cause the frame to bend. Everyone knows how a lever can apply considerable force. The RAM designers were concerned this might occur so they added brackets strong enough to counter such a force. This is most likely why the brackets exist.

The Right-On replacement brackets are probably not quite as strong as the OEMs overall, but they are still probably strong enough and should be more than adequate to protect the frame. It's probably very unlikely that you or anyone else will ever sit on your MFT doors when open or that such a weight will ever be applied, so you'll probably never need the bracket's protection. However, the RAM designers couldn't take such a possibility for granted, so they had to account for it. In normal use, the brackets probably serve little to no function.

Thanks to @securityguy for coming up with this initially. I was racking my brain trying to figure out why the brackets were necessary. I never imagined anyone would be foolish enough to sit on the end of one of the doors when open, but given the crazy things that can and do happen, you can't ever rule that out. It's also possible that someone might apply another such heavy weight with the door open such as when loading a heavy beam or something like that. So, the brackets serve as a fail-safe for excess loads applied on the MFT doors.

For those concerned about the strength of the right on brackets, also consider the RAM brackets are engineered assuming nothing else added. We are adding a cover with rails and header that increases rigidity.

Damn, a week too late, lol. Finishing up the install of the Bak Revolver X4s, will post pics and details later, but it required the right on brackets and some modification of the cover rails.

Did you also add the countersunk bolts to the new brackets?

 

[dpcarey32]

Kooch - your post said you had issues when it closed with something not flush I thought? Was that resolved? Your image on your truck looks awesome, I have order the flat allen wrench screws already. Supports are next.

What size are the flat allen screws and where do I get them?

 

[securityguy]

I bought really nice stainless T304 countersink bolts to install my RO brackets. Once I saw that there was plenty of clearance to install my cover, I sent them back to Amazon and just reused the OEM bolts from the factory brackets. Unless your cover is going to create a VERY tight tolerance, which would really surprise me, these countersunk bolts are totally unnecessary.

Any issues with closing the tailgate with the cover in place? Looks great!

can you share what mods were needed on the rails? - thanks anxious to see the images

Successfully installed the Bak Revolver X4s hard rolling tonneau using the right on brackets and some modification. The recessed bolts were not necessary, which is good because the ones I had ordered were way too short.

Note on the right on bracket, the cutout for the painted bolt and washer is snug fitting, if you tighten the bolts behind the cab first it should line up, then tighten the bedside bolts.

Now the good stuff. In order to make this cover fit as intended I made two cuts to the rails to fit around the right on brackets so the rails would be snug to the bedsides. Here’s a before-ish shot (had started the cut):

I cut the part of the rail that goes against the bedside about 4/5 ribs down and 10” from the cab end to notch around the bracket. I also cut off the silver tab by the spring that goes against the cab side. This tab sets the depth and would have pushed the cover too far towards the tailgate due to the thickness of the right on bracket. After shot:

Here you can see how this fits around the right on bracket now:

This part may not have been necessary since I later moved the cover slightly towards the tailgate to snug the seal up against the tailgate. The springs were rubbing against the bolt in the right on bracket as seen here:

To fix this I relocated the upper end of the spring towards the tailgate. A recessed bolt would also work. On the driver’s side I moved the spring into the end of the slot for the cover bolts.

On the passenger side I drilled a new hole about a half inch over.

Bak provides a thicker and thinner strip of foam to seal along the cab side of the bed. You’ll use the thicker one, but in my case there was a little bit of a gap between the side rail and the gasket. Hard to see but there is a little bit of light under my finger:

I used some of the thinner gasket attached to the bottom of the rail to fill this in.


At this point the cover can be installed as normal. Here’s a shot of everything bolted up. I attached the strap clamp on the right on bracket to get it in a better spot. Took some convincing to get it tight on the smooth metal but it’s secure enough for the strap.


Too many attachments, will follow up with final pics.

Couple of notes.
- You will have to guesstimate on how far forward/back to install the rails since the tab that goes against the cab end was removed. As mentioned I ended up having to shift it towards the tailgated once I had the cover on. Just make sure both sides are at the same distance front/back so things square up.
- The rail ends were uneven at the tailgate for me. One side was a bit high leaving a gap and the other too low causing the tailgate to hit it. With the rails bolted on a few good pushes in the right direction flexed the bed side enough to line things up nicely.
