So far so good, no more wet floors in the back of my 2017 Ram 1500.These were SLIGHTLY thicker than the OEM ones, they had larger support tabs on the back side which makes them more rigid that the original ones. That would be better but I replaced these by fishing up between the bed and truck's cab then pulling into the hole (after removing the rear seats for access of course). The correct way is supposed to be by pulling off the bed....which I wasn't about to do. So I had to shave a little from the back of each one so they'd slide between bed and truck, before they just got wedged in. Not the product's fault by any means, just worth noting if you are lazy like me ;)*Some people claim you can bend the vents so you can install them though the inside of the truck but I for the life of me couldn't get that to work either. Again, this has nothing to do with the quality of the vents. Might actually speak to how well made they are they don't bend / flex enough.

2010 Dodge Ram 1500. Perfect fit. No more water in my truck.

The vents were a perfect fit. Good quality. Easy to install.

These can be pulled up from the bottom with a thin string attached to the top holes in the 2 upper clips. It is a little snug, but once you can grab it from inside, you just pull it into place. Up and then sideways into hole. I put a little thin coat of grease on seals so they will last longer. I just moved seat all the way forward after unbolting and there it plenty of room. Front seats all the way forward Even took out carpet and dried it out while work was being done.Used a fan to help dry it out. Bolts are 18mm and locktite was used from factory so they can be tight to get out. A little grease on threads and they go back in easy. Utube has videos.

The flaps are cheap and if you go down a dirt road dust will get in the cab, you will see the dust particles when hit by sunlight. Might be good for rain but not if you drive on dirt roads
