Installed the HD unit on my 2012 Raptor. Looks great.

The adjustable / locking securing mechanism on the leafs which tilt are definitely light weight in my opinion. The adjustable slotted plate legs where the engaging rod travels through to travel under the box lip has to be securely torqued down. Due to vibration and the weight of the cover and movement due to the flexibleseal the side clamping plates are under a good load. Once they get loose the lid vibrates a fair bit and needs to be retightened.

I wonder at what pull load the cover lid would lift and bend the 1/4" or so engaging rods which prevent the cover from flipping up.

I don't like the exposed hinges or the bulky locking/twist mechanisms. Just the wrong profile to expose to a deck which is used for hauling and transporting things.

I think Diamondback fell short of a good idea. At the price these things should be incorporated.

The last thing is the bolting of the hinges to the diamond plate without taking down the diamonds so the hinge seat is nice and straight. Current finish with gaps and slight tilts looks sloppy and without a high degree of fit and finish. Bad mechanical joint. I guess the 5min to knock down the diamonds under the hinges was too much to ask on a $1600 cover.

Still there doesn't appear to be any options on the market so you take it as it is....

 

Should've shopped better. I got my HD for $1300. Every cover will have its problems. My current Leer topper that came with my current truck leaks, doesn't close properly, and one window doesn't work. But I agree with the locking handle, that was a bad design

 

The line-x drove the price up. Relatively speaking I don't think there is a more expensive top out there.. is there?

 

I believe the pace edwards roll ups were more or similarly priced. The Undercover looked like a cheapo cover, it was cheaper. The painted fiberglass I believe were similarly priced, but I worked my truck and that would've been scratched to hell. I chose the diamondback HD for strength and easy removal and install. Fabric tonneaus were not even allowed to be in the mix.

 

Undercover (Classic, SE, and LUX) are great covers and are great bang for your buck.

Diamondback is a different animal and is good also, but you should keep an eye on the Diamondback cover's seals. The latching mechanism is a bit rough, but it works.

 

I will say I needed to put down new double sided tape after 2 years on one of the seals but that cover NEVER leaked on me. Oh yea my Leer cap's window seal is falling off. They all wear out eventually. Each cover manufacturer could make the choice to use better seals, use all stainless hardware, better locking mechanisms, better struts, and the list goes on.

 

The covers seem very sturdy.. A friend of mine has one on his 250..

 

Now I know It's an old thread but this is my Diamondback HD ATV bed cover






This next photo is not normal you are not supposed to have the side rails on,
and the Low Profile Cab Gard on at the same time so I bought the side rails in just a bit
so I could have them both and I think it looks finished this way.



This is where they leak One Day when I get around to it
I will open the Lids and just stick some black silicone down
and when it drys the lids should squeeze up nice
(I never intend on tacking this cover off)

I whacked some LED lights in underneath the cover which are real good for cooking on the tailgate when we go real camping. We just lift the back cover prop it with a broom handle throw a big tarp over the hole tray tie it off to a tree or two peg the tarp down at the front and role the swags out. I'll post some more pics next time we camp
Here is a You Tube video of my bed cover
All up this cover cost me way to much, so don't you blokes is America complain

 

I just spoke with a Line-X dealer he quoted 1780.00 for the Diamondback 750 line-X. I do have a Century Royal topper and will sell ASAP! After all I've read and seen I want that cover.

 

I thought I would mention that Mr-Earthmover's Diamondback doesn't look like it has LINE-X Premium on it, it looks like standard black LINE-X. Premium is a darker black and won't fade. You can order the Diamondback with LINE-X Premium on it from the factory. Or not and the LINE-X dealer can apply it.

 

I didn't know there was a Line-X Premium grade
and it was not offered to me and I have to say
I'm glad I didn't because I would have got it.
If you notice all the black plastic bits on the bed sides and
on the bumper they are a pretty close match
so fallows just be aware of that.

 

They are easy to install so unless you were planning on having them install it you can get a much better price ordering directly from Diamondback. When I was looking at it I spoke to them several times, their customer service was always great.

 

Thanks for the info
