I got you. I considered a roll up one until I saw how easy it was to install and remove the Tri-Fold, plus I don't think I'll use the whole bed much but if I do the Tri-Fold can be removed pretty quickly. To each his own though, get what you like.
Yes it has a rail that clamps down each side of the bed. My truck has trail rails so it clamps into those, or to the bed rails. Mine has not been 100 percent water tight, but Ive never had a tonneau that was, I think adding a bit of weatherstrip to the front of the bed would help. Im happy with it in that regard. It looks better than any trifold Ive owned- those never sat very flat. You can adjust the tension of the cover without tools to adjust for winter vs summer etc... JCR has a few videos showing their bedrack with the cover- you just add a bit of weatherstripping between the rails and bed to take up the gap from the bedrack brackets. Rebel has also said it will work with the xplor rack as well- I honestly think any bedrack that attaches similarly would work. For the money I dont think you can beat it, I personally dont like how the mopar looks sitting over the bedrails. Access has other models that work the same way- the literider is the least expensive, I believe most of the differences on the higher priced models are the fabric quality/thickness and latches.
The T1 part number is TG-BC1C9012 -- Here is the Amazon link. I opted for the Amazon "Used - Like New" which was about $154 at the time. Amazon will say it won't fit but it does. Make sure it's the 5'2" 05-18 version. I've been running this cover on my JT for 3 months. Decent buy for the price but I will eventually upgrade to a hard cover (security reasons) that doesn't obstruct the bed rails (to fit a bed rack).
I just got and installed the Tyger T1 of this P/N, fit isn’t perfect but it will do for now. Will also probably upgrade. A cost effective solution is good now as there are other accessories needed in the near term too
