I had the Mopar all-weather mats in my '19. They were great. But, they did not cover ALL the carpet or the door sills.
For my '21, I got the Husky all-weather mats. They cover pretty much ALL the carpet, and most of the door sills. The fit is really great and they seem to very heavy duty and will hold a lot of liquid, in case of spills. But, one thing I have to credit the Mopar mats for is stuff did not slide around on top of them. I had a case of bottled water on the back seat floor in my '19 and it never slid around. That same case of water is back there in my '21 and it slides around a lot on the Husky mats.
As for bed mats, I went to Home Depot and got a $30-something dollar 4x6 commercial door mat for my '19. I have RamBoxes, so my bed is rectangular. I trimmed a few inches off the mat and it was a perfect mat for the bed of my '19. Nothing slid on it at all.
For my '21, I decided to splurge and get another one of the same. They are now up to about $40. My old one was still in pretty good shape, so I put it in my '21 and put the new one on top of it for double thickness.
For a RamBox bed, I don't think you can beat the Home Depot mat.
