I first put a Bak Roll X on my 2015 GMC Denali, then onto my 2017 Denali and just put it on my 2020 Denali. I verified the current Revolver II for 2017 and 2020 were different p/ns. I finally found out there was a 1/4" difference between the two versions. I was going to install the Roll X on the 2020 first, before I shelled out another $900. for the new version. I figured if I need 1/4" or 1/8" spacers, I'd have my companies' tool room make them up for me, but I didn't need them. I installed the Roll X and took some time to adjust the unit to cover the tailgate, which meant at the cab end of the cover was closer to the back edge on the bed top rail, but it sealed fine. I have no illusions that any cover is water tight. Don't care as after 5 yrs seldom get more than a few drops of water. After installing the cover, that night we had a hell of a rain storm.. over 2" of rain. Next morning there was a pool of water on right side of the bed, behind the wheel well. I contribute that water to the stake pocket openings. The stake pocket covers I though would fit from the 2017 do not fit,,, seems GM downsized the pockets on the redesign, so waiting for new ones to arrive. I have no complaints on the Roll X cover, only issue is Bak attached their label to both sides using carbon steel pop rivets, which are totally rusted. Yet, if it bothered me enough, I'd drill them out and reattach with stainless steel pop rivets. The tail gate closes fine. with the whole tail gate or with the center portion only... Will reply back once the stake pocket covers are installed to see how the leaking has changed...

I installed a Roll X on 2015 Denali, then onto my 2017 Denali. With the lease running out, I went to Baks website and looked for the Roll X, now called Revolver II or upgrade model Revolver 4. Found that the p/n for the unit was good for models through 2018 as with the style change in 2019, there was a different p/n for the 2019/2020 Revolver II. I pressed on and tried to find the actual difference between them. Finally, I got someone to respond, to say the newer versions are 1/4" wider, due to the bed change. I wasn't going to drop over $800 for 1/4" difference as I figured I could easily shim one rail side a 1/4" or both rail sides 1/8". So decided to try to install the Roll X onto the new 2020. I installed it yesterday. I was prepared to shim if necessary.. but there was no need to... It fit fine. The cover is now over 5 yrs old. Living in upstate NY, the cover gets plenty of snow and salt. The only issue are the plated bolts they supply for the clamping. rust. changed all the hardware to stainless steel, so no corrosion should happen going forward. The cover is still in good shape, and the underside material remains in place. The only complaint is BAK pop rivits their name tag on each side of the cover by the tailgate and those pop rivets are carbon steel and rusted... for 20 cents more they could of used stainless pop rivets.. minor issue just annoying.. cover is dry, but always some drips, usually from the rail stake pockets.

seems the drivers side power running board sometime works when opening the door, but sometime while standing on it, the damn =thing will stow itself, forcing my feet to slide off the step, other times it will extend and re-track before I swing one leg out when getting out of the truck. IS there some switch or sensor that uses the opening of a door to activate these steps? anyone else having these issues?

truck would not heat up today.... temps in the 30s and dang cold... tried every switch to try to get some heat?

Dealer told me that my 2017 Denali 1500 with new 8 sp tranny, its the tranny and GM has no answer to this problem. I did not have this issue with my 2015 1500 Denali(6 sp) was told to drop down a gear or push in button for hauling a trailer and the mis-fire /hesitation will disappear .. well, I'm not going to burn more gas using the towing feature, GM just needs to come up with a fix... $60+K truck and it shutters....

took back the 2017 1500 Denali w/ 5.3 and 8 speed with only 1200 miles due to the misfire, surge, as described in this thread... dealer is saying its the 8 speed tranny. If I use the +/- button on the shifter and kick it down to 6th, the surge/misfire will go away... something to do with software on tranny and 5.3L engine.... they "claim" they were surprised this 5.3 was built with the 8 speed... I really could care less if it has 6 or 8 speed. I just want the misfire and surging under light load to be eliminated/fixed.... dealer says GM is working on a fix.... yea, like when? 1 month or 11 months from now? its a freaking $63K truck, both the engine and tranny are not THAT new..... they should be able to re-write the software... WTF GM this is totally unacceptable... if I wanted a POS, I would of bought a dodge or ford

have had Roll-x installed for 15 months. no problems. located upstate Central NY... I try NOT to roll the cover when its below freezing, as who wants to do hauling stuff in those temps. It has been rolled when below freezing, just not very often. again no issues. I did run black RTV under the rubber edges from the front of the bed to where the covers when rolled back stops. This has stopped the very minor drips I use to get when it poured out... overall 100% satisfied with the Roll X cover... I think it has the lowest profile on the market besides...

Not sure if the AC is lacking freon, but it seems the passenger air vents blow HOT air and the driver side cool air.. cycle the different options to see if this will redirect or shut off the hot air coming out of pass side, but no changes.. I think this happened a month ago and cleared itself up, but now, even with turning the passenger side thermostat to 65, it blow hot air ??? is there a service bulletin out on this problem?

suggest contacting Morrie at BAK Factory Outlet.com [email protected] he has been a real good guy to deal with. I have Roll X and it is a great cover. no issues

I got 7443 amber and red for the Denali (front/rear), error codes right away. only solution I know of is to add the load resistors which I will NOT splice into the wiring harness. Maybe there will be a direct swap with 2016 Sierra, which suppose to have both LED rear and headlights...

ok, popped the hood and found the fuses, but can't figure which is the one to remove to add the EP29L? turned on the turn signal with engine off, and can hear the clicking sound, but touching each larger fuse block, can not determine which one it is. And from the pictures on the internet of the EP29L, they all appear to be much larger than any of the ones in the fuse block? in reading the listing of fuses, I can't determine what the name is either??? thanks ahead for any help

got 4) 7443 red and 2) amber for the denali from Carid Lumen plasma LED at very high price $30.PER bulb! their website clearly states: You may have heard horror stories from folks that have replaced factory halogen bulbs with LEDs only to find these new bulbs caused "bulb out" error messages, worked sporadically, or triggered check engine light. Because your fog lights are controlled by a specific module that is in series with other vehicle control computers, something as simple as an improperly designed bulb can break the loop of data communication telling your main engine controller all systems are go. Lumen bulbs are CAN Bus compatible, and have been designed with a higher level of advanced technology that allows proper data flow – so they'll work right every time with no error messages, and without confusing any computer controls. CARiD also offers Lumen replacement LED bulbs for daytime running lights, parking lights, backup lights, and turn signal bulbs." Well, installed just right tail iight and flicked on the turn signal... hyper-flash and alert on dash the bulb was out... so their hype is BS. and these bulbs are just ordinary LED that causes issues with low voltage draw. Now I'm in contact with CarId to return them. I am also thinking about going to find a flasher EP29L which is suppose to correct the hyper flash and signal message... A) where is this thing located in the 2015 Denali and B) has anyone installed this EP29L and did it stop the problem? Different sites on line say this item is not compatible with 2015 GMC Sierra.... WTF... something has to be available when switching to LED replacments ???? any help out there? thanks

Thanks Victor for the answers on LL & load resistors... quick follow up question, with the Denali w/ the brake controller option, would the VLED's flasher unit be necessary? Just not sure with that package, the truck came with a H.D. flasher? Truck DID not come with the trailer package.. just the brake controller??? thanks again

yanked this toy from work to home (20 miles) hardly knew it was back there !!
