Hi folks - I wanted to add some info to the thread. I have just changed covers from a Solid Fold 2.0 to a DiamondBack SE on my 2020 Limited with MFT, no Ram Box. While the Solid Fold was "ok" , I wasn't super content with it. Some small leak points but really I was not comfortable with security at the tailgate. It seemed to me that it could be compromised with little effort by someone wanting to break in to the bed. Also I started to get a depression (dent??) on the top of the cover at the right side cab fastener position. Not a big deal but sort of goes toward overall craftmanship and quality.
The Diamond Back SE was about $1,000 more expensive, but I have to say, the quality shines and really comes through - so I'm ok with the price difference. I got the newer matt black finish and I think it looks great. The dual "butterfly" style opening had me a bit concerned but I bit the bullet and went ahead with the purchase. Glad I did. The dual opening style is fine for my purposes and really opens more than I thought (or could tell from the website photos). It's made in PA, USA and it is really well built. The fit and finish is an order of magnitude over the Solid Fold 2.0. Plus it has a separate locking mechanism for the front and rear butterfly panels. I haven't been able to test the weathertightness yet but will soon. On the downside, the installation while not at all difficult, does take time because you end up using the OEM bed brackets at the cab for the locking mechanism for the front cover segment. It takes a lot of time, trial and error, to get everything positioned so as to get a good weathertight seal. It took me over 2 hours for full installation, while they say 45 min in the instructions - so maybe it's an operator issue
...
This bed cover is clearly not for everyone, especially if you're going for a low profile look. But if you want to use OEM brackets and want a substantial cover, it may be worth a look. They also have an HD version that can carry an ATV on top (I think the weight limit of the HD is like 1,600 lbs versus the 400 lbs for the SE). And finally, for disclosure purposes, I am not associated with Diamondback Truck covers at all, I simply wanted to pass along my opinion and findings. after installation. Cheers!
