I finally broke down and ordered the Diamondback HD bed cover for my longbed DCab. After months of soul searching and having made poor choices in the past I paid more money up front with the idea the extra cost would be an insurance premium for future use. Only took a week to deliver and had great dealer to work with. Installed it two days ago.
I really, really like this thing. Even though I bought the HD model I had no problem installing the cover myself in about an hours time of slow, methodical planning and execution. Could do one now in about 20 minutes. Can take it off in it's entirety in about the same.
Options I ordered (not shown in photos) were the heavy-duty cab guard (ni headache rack) and the optional side toolboxes. I am having the tool box interiors sprayed with bed liner so they aren't installed yet. And I didn't care for the looks of the HD cab guard. I am swapping it for the standard low-profile cab guard. Just a personal preference and there is nothing wrong with the heavy-duty guard.
Here's what you get at the loading dock when it arrives:
The two tool boxes seen in the rear of the truck are Geneva truck drawers as sold at Northern Tool and the ilk so don't confuse them with the Diamondback tool boxes I have yet to install in the front. I always use them on my trucks as I loath dealing with a behind the cab saddle-type box.
Here are some more details:
4 Clamps are used to hold center section down on bed. These are the ones designed for the factory cargo rail system but normal ones are also included in case the truck doesn't have cargo rail system. The bolts provided by Diamondback were about 1/4" too short so I replace them with some longer cad-plated grade 8 bolts I had laying around the shop. Maybe the originals would work after the seals have set for some time.
All three panels have heavy-duty aluminum beams traversing the span of the bed, providing the Diamondback factory weight rating of 1,600 lbs.
I'll probably never see that much weight on the cover but may haul an ATV or occasional pallet of material on it. See in photo below for Japanese mini truck in background, which may eventually find it's way up there.
The front and rear panels are locked down with lock rods that engage into the OEM cargo rails. Here is a view of the front panel lock rods:
Here is a view of how the lock rod engages the OEM cargo rail in the rear (removed my plastic rail plug for a better photo):
The tailgate can be opened and closed with the cover down and the tailgate compresses a seal along the trailing edge of the rear cover. Here's a shot of a rear corner:
I am very pleased with the cover with only a couple of minor nit picks at this point. I am a little concerned that the latch handles may get damaged if I have a forklift slide a pallet onto the back. It would be nice if the handles were flush to avoid this. I'm not too concerned but will have to watch carefully when loading the rare pallet.
Needless to say I won't be carrying any long loads like lumber or railroad ties atop the cover until I get the new cab guard installed.
All in all I am very happy with the cover. When it and the tailgate are locked it would be an intimidating endeavor to break in. When the cover is removed it comes off cleanly without any itinerant hardware left on the truck.
I'll throw a couple of more photos into this post after I install the tool boxes and cab guard.
