If you want Rhino...OK, but if you want a color match, you might be better off with LINE-X, here's why:
Rhino dealers can apply colors in two ways, with Solarmax or another product with a urethane based paint as a topcoat. Solarmax (which actually is not a Rhino product, it's made by Bayer and Rhino just gives it a name) is a decent product, but they MIGHT not be able to get to the exact color because they are limited to about a 30% pigment concentration. So, if they can't hit the color with the 30%, it won't match. If they use another product (Tuff Grip, Hardline, Tuff Stuff, etc.), then they will topcoat it. The problem with this method is that urethane based paint is NOT durable enough for a truck bed.
LINE-X Xtra is not limited to the 30% pigmentation and it is durable enough for a truck bed. Rhino does not have a product like Xtra.
Here's Solarmax. The bedliner looks good, but it really doesn't match the truck well, not enough blue pigment.
Here's what can happen if you use a urethane based paint as a topcoat. By the way, this is probably Rhino Tuff Stuff (low pressure).
To compare, I'll throw in a blue LINE-X Xtra pic.
Here's a really difficult color, Ford's White Sand Metallic or White Chocolate Tri-Coat:
