I have a 2020 crew with ramboxes, been looking for a cover since September. I decided to go with the BAK Revolver x4. It's a hybrid,hard cover that rolls up.
We had terrible luck with the canister type covers, don't really like the section flip types but needed the security of a rigid cover so i tried the Revolver.
I went to their sales page direct on Cyber Monday and was able to do a chat and negotiate it down to around $850.00, free shipping
I've never installed a tonneau before but The install was amazingly easy with the factory rails that come on the truck.
Slid in the left and right main rails, installed bulkhead gasket, rolled the cover out, adjusted the cover to ride Parallel and tightened it down. It might have taken an hour and i wasn't rushing..i did spray a little simple green on the right rail too make it slide on the factory rail easier. I did have to loosen the driver side factory ram rail and lift it about 1/8 to make the cover rails level.
The ramboxes create a pocket behind the tail lights and that pocket is still exposed after the rails are installed. I don't know if any of the covers out there have molded a wing to the end of the rail just to cover this pocket but Bak included a bunch of weather strips that you can cut and stack to fill the gaps as you see fit. They don't tell you what all the strips are for in the instructions but I'm glad they included them. I had to double up in some areas to fill the hole completely.
When it's all said and done the cover is ultra low pro and a dull matte. It matches the plastic on the truck well. You can open the ramboxes at any point of openness with this cover. You can roll the cover from just 1 side of the truck, you don't have to go back and forth. It takes about 10 seconds to release at the rear ,roll up and click the straps to secure for driving while rolled up.
Can't speak on the durability, i just installed it last week. It seems plenty beefy and there really aren't many parts to fail... Hopefully.
