I've heard Line-X is very good as well but haven't had experience with it. Rhino Liner is a great product, you'll be happy either way. Back home one of the company trucks had Rhino liner, we bought it used that way, beat the crap out of it for a few years then sold it, the liner still looked new after a quick wash, just a tiny bit faded from the sun over the years but not bad. I have Rhino over the rails on my Dak, the place I got it sprayed at told me the newer formula is more resistant to fading and they also sell a product that can be applied to it which will bring a faded liner back to looking like new. My friend's dad has his 2nd gen Ram rhino-lined and pretty much all he uses the truck for is hauling cut up lumber out of the woods behind their house, hasn't screwed up the liner yet...

I would personally avoid the drop-ins, had one on my old Chevy and it caused more damage to the bed than I probably would have done with no bedliner at all.

 

Line-x is a great product and there are a few differences to note between them and rhino. Line-x is sprayed at a high temp and high pressure, so it doesn't run like many rhino liners and line-x also guarantees a certain thickness on you bed. Both are guaranteed nationwide now, but I prefer the line-x. I have read that rhino is generally softer and more rubbery than line-x, I don't know if that makes a difference to you or not. I just got my bed, tailgate, and rocker panels on my truck done in line-x and love it. Check it out https://dodgeforum.com/forum/v6-spec...er-panels.html
