AFAIK there were no interior changes from 2014-2015-2016. Some of the options like charging lid on the 2016 may make a difference in the wiring required.

Ha ha yes that could happen. I've done this mod on all my vehicles since I started driving, so I'm used to it and rarely forget to unlock. This one was by far the most difficult.

Modified the factory alarm to trigger on locked entry handle pull. Details here http://www.gm-trucks.com/forums/topic/177069-help-with-alarm-trigger-mod/page-3?do=findComment&comment=1693523

The covers are made by third parties. If you show a picture of the clamp maybe someone will recognize the piece and suggest a manufacturer that uses same part. Then you should be able order a spare from them.

Does the drop in liner fit under the rails? If so most of the folding covers should work, but routing the drain tubes on some may require drilling. I have an Extang Solid Fold 2.0 that does not require additional side rails or a drain tube. I was able to get it for $760 from an authorized dealer and it was shipped directly from Extang.

A mention of tonneau effect on aerodynamics is in this article. http://www.torquenews.com/397/gmc-busts-top-4-myths-truck-aerodynamics

...or just take a crowbar and pry the cover up since the latch plates are held onto the aluminum skin with small screws. Really though, if anyone wants to get into any cover they will figure out some way to do it. That Diamond Back looks like a pretty tough unit, but a little too industrial looking for me and fact the center panel is stationary is inconvenient for my use.

Securing content under a cover was my concern as well so I hooked into the factory alarm and added a switch to the tailgate handle. This works on the assumption that a thief will try to open the tailgate before attempting to force open the cover. Video

When I did my alarm mod I revisited the Pop n Lock and found that the reason the mechanism can be sticky is that the replacement plate is too thick. By shaving it down a hair (I used a Dremel with a sanding drum) it now swivels freely with the C clip attached. This free movement is needed so you can lock and unlock with the key and return the key to the center position without disturbing white locking mechanism. (Here is a link to my alarm modification that leverages the locking tailgate in combination with the factory alarm. )

These are Westin stainless steel 4" oval step bars. They attach to the body mounts. Got them for a bargain price via craigslist locally.

Oh yeah you should be fine. A tonneau was the same reason I wanted it as well. The only piece that needs to come up is the door sill and wire cover underneath. Take your time on each tab on the near side. The opposite side are the same tabs but once one side is up the other side is easier as you are then just shifting the whole piece towards you. As others recommend stagger the location of your solder joint to each wire so you don't end up bulking up that spot, the wire bundle is already jam packed as it is. (May be more of an issue for those who use the included connectors.) Good luck!

The tailgate part is pretty easy since it is just unscrewing a bolt and replacing the lock lever. It takes some finesse to get it to move smoothly so you may have to play with that a bit. The running of the wire to the front requires getting under the truck and zip tying along the way. Connecting to the correct wires, and what approach you use will depend on your experience. I am comfortable with soldering so that was my method, but the kit comes with slide on connectors which are easier but may not be as secure. Fondupot's video is a good resource.

I tried but the clip would need to be modified. IIRC it has an extra tab that fits into the OEM lever to keep it in place. The delay you describe is what I first experienced as well. If the lever is freed up it swings further on its own so there is no delay in the white plastic piece flipping over to the lock/ unlock positions. When you have a minute try other positions on the C clip and see if you can make it work. I added some WD 40 as well.

Is the key not locking or unlocking? I feel the c retainer clip is too thick for the slot on the cylinder so it doesn't allow it to rotate freely from either position. I had to try a bunch of different positions so the metal lever would have the necessary play to allow locking and unlocking with the key. When you lock or unlock, the lever should be free enough to stay in place when you turn the key back to vertical to extract it.

For those of you that used a wire for this mod - what gauge solid wire did you use? I'm assuming you used solid wire to be able to push it in? Or did you just solder tin up some stranded wire?

I have a little over 1000 miles on my truck now and have gone through a couple of tanks of 87. The truck feels like it accelerates and shifts smoother now than when I first got so either it has broken in, it has 'learned' my driving habits, or I have adjusted to its idiosyncrasies. In any case I am loving driving it and I'm getting better mpg than my old f150 so I am very pleased. It is a 5.3 with the 3.42 rear end, 2wd.

I have never had to remove the tailgate on any of my previous trucks but now that you mention it I will have to go back and see if I should make some adjustments. Thanks.

Thanks to Moto Medic for the post and fondupot for the video and others with the helpful tips. I installed the unit this afternoon. The cam gave me a bit of trouble, with the c keeper it was too tight at first and would not swivel to allow locking with the key. It took me a while to be able to place it just right and I had to shoot some wd40 at it to make it work to my satisfaction. I found the larger tan+yellow and grey+green from post #50 to be the correct wires in my Silverado I used the 'solder at the door sill' method and came up through the grommet under the driver mat. I poked a hole with a straightened hanger, then used a cheap stick pen with the ink tube removed to push the hanger back through the grommet from under the truck. Once the pen is halfway through the grommet, I stuff the wires inside and push the pen rest of the way into the cabin, with the cables along for the ride. The grommet tightens cleanly around the cable this way. I have my truck settings to unlock everything with one click, as I regularly forget to click twice and feel stupid when I yank on the back door to load something and the door won't budge

Wow that Diamondback is some heavy duty cover. Hadn't even heard of it till now. It would be overkill for my needs but let us know how it turns out when you get it.

The Solid Fold 2 does remove easily but it is an extra step and you will need space to put the folded cover when you take it off. It works for me as I rarely need the whole bed open.

We had our first steady rain with the new Extang Solidfold 2.0 and I got water drips under center of the last hinge and near the front right clamp. There was not much in total amount of water ingress and it rained pretty steady for a day. It had not leaked in the last car wash so I will call Extang to see what if anything can be done to make it more water proof if possible. I kinda expected that it would be difficult to make these folding covers water tight.

Look at UQA option on this page http://media.gm.com/media/us/en/chevrolet/vehicles/silverado/2014.tab3.html Bose Sound with 6 speaker system, (7 speaker system including subwoofer when ordered with bucket seats)

Do you have a picture? I didn't get this option at my dealer.

I ordered the Extang Solid Fold 2.0 last week and received it 5 business days after ordering. The cover I ordered is model Extang 83450 Solid Fold 2.0 Tonneau Silverado/Sierra 1500 (6.5)14-15, 2500/3500 The outfit I ordered from on eBay is pickupsurplus.com who also have a web store at TruckProUSA.com I decide to order from these folks as they had a 'make an offer' option on the lid on eBay and I was able to get a price less than the other vendors and use a Paypal no interest offer. I called to speak with them at their store in Alabama prior to ordering and felt comfortable with their explanation of the shipping process. In my case the cover was not in their stock and would be shipped from Extang directly. The cover arrived in good condition via Fedex with the box showing some transport bumps, which I documented before opening the box just in case the cover was damaged. Fortunately the cover is packed well in the critical corners and edges, although the main sides could use more protection. In this situation the box was not damaged in this area so it worked out fine. The cover appears to be well constructed and the rubber seals are thick and mold themselves to the truck bed well. It does appear to be assembled by hand and on close inspection I noticed a couple of spots of glue on the frame, they are not noticeable if you dont know to look for them. My truck has a sprayed in liner and the front of the bed is lower than the side rails, so in the front two sides there is a tiny triangle of open space where the seal transitions to the side rails. We don't get much rain here in So Cal but I will keep an eye on this and see if I need to address it for water intrusion. There are other openings in the top front of the bed anyway as well as around the tailgate that I would need to seal up if I want to make it water tight. Installation of the cover was a breeze and I was able to do it without assistance. I selected this cover because I did not want to have to install any side rails, so all you need to do is attach it via 4 clamps. These use a long bolt and some sort of reinforced plastic clamp. The two front clamps are a hand tightening style and come with a warning attached that says the handle should be tightened two turns only after contact with the bed is made to avoid disfiguring the top. After positioning the lid evenly on the truck I tightened the front clamps I read a review where a user reported that the cover shifted if not tightened down enough, so I decided to add a square piece of rubber from an inner tube in between the clamp and bed side to give it a bit more grip. I have taped a couple of marks on the position of the cover and will be monitoring it for any movement. The overall fit of the cover is good, although I did notice that one side of the cover appears to sit just barely longer compared to the other side when you run your hand at the edge of rear corners of the truck. Again this is not really noticeable but someone who is very picky might be bothered by it. Not sure if this is an issue with the square of the truck bed or the lid, but I had a similar situation in a hard lid for my previous truck and I have come to expect issues with tolerances on vehicles and accessories like this in general. The rear of the cover is fastened with spring loaded hand clamps that fit into a position right next to the end of the bed. The positioning of the rear clamps is exactly where it needs to be on this truck as any shift fore or aft and it would be blocked by the bed corner or a rail support. Because the rear clamps are spring loaded they do allow the lid to be slightly lifted in the back when clamped. There is a video of this in action on utube, but my lid only allows about half the travel his video shows, perhaps due to closer positioning to the end of the lid on our Silverados vs the position on the Ford. I think there may be a way to limit the spring travel by either tightening a lock nut at the base of the handle or inserting a spacer, but after closing the tailgate the allowed lift is minimal so I am going to leave it for the time being. In the folded position the cover is held by two straps that clip into receptacles held by screws at the front edge of the cover and it appears secure. Rear visibility in the folded position is unobstructed as I can still see the very top of the tailgate through the rear view mirror. In the folded open position there are 48 inches uncovered on my 6.5 foot bed. I will be ordering extra clamps and strap clips to have on hand as spares just in case, as I plan to keep this cover past it's support life. Overall I am happy with the purchase.
