Mine has a Xtreme Liner that the dealer had sprayed in as part of the deal on the truck.

 

I have had both Rhino and Line-x the Rhino is softer and tears easier. I couldnt figure out why they wouldnt spray a harder product till I tried line-x and saw the difference in the machines they use. Rhino uses low pressure so they have to spray a soft product. Line-x uses High pressure my dealer says it sprays at about 2000 psi and uses high heat also. Thats why their mateial is so much more durable. I must say I have yet to knick the Line-x in either my last truck or the Line-x xtra in my newest truck. The Line-x xtra has the Kevlar coating in it made by dupont. and man they were write the shine doesnt dull out and its now been over a year. The other neat thing about Line-x is that they can do grapics in the liners if you want them check out this colts liner my local dealer did.

Not to mention I have yet to see a white Rhino liner.... Anyway that is my opinion after having both... Also on cost the average liner is $400 - $500 But if you are going to get one only go with those two name brands the rest dont have a nationwide warranty. They all claim lifetime but it is dealer specific and has exclusions.... Only Line-x and Rhino have Lifetime and Nationwide warranties.... So pick only one of those two forget the rest..

 

ok, so I called my two local dealers

Rhino over rails $525 w/ Costco Discount of $50
Line-X over rails $540

leaning towards Line-X but it's still hard to call after reading all of these. Seems like you cannot go wrong with either, with their standard stuff they're both going to fade, but both have the lifetime warranty...

 

Actually Line-x wont fade it just dulls out or wont glisten after a year unless you get the Line-x Xtra with Kevlar then they guarentee it not to even dull out..... for Life..... Thats what I went with the second time of getting Line-x and man after 1.5 years it still looks as good as the day I put it in and I dont keep it covered.
