Line-x and rhino are similar. Line-x has more texture. Up until a couple months ago line-x was the only bedliner to offere a NATIONWIDE warranty but now so does rhino. Black is the most UV stable color that is offered, all colors will fade to a different color over time. light colors I.E. white are the worst. The hardener turns yellow over time and black is the only color that hides that. Colors can be done but a top coat of urathane paint has to be sprayed on top to keep the color true. Line-x wieghs just a little more that water per gallon (8.4 lbs.) depending on the bed size line-x might add 20-30 pounds. other wise all toyotas with line-xed beds would sag in the rear.
