I got a Summit catalogue this week that has a front bed protector in it made by Deflecta-Shield. They carry a front protector, front cap, full tailgate protector, and a tailgate cap for the Tundra. The front and tailgate protectors are $69.95 and the caps are $19.95. I've been thinking about getting the front protector and full tailgate protector for when I haul my ATV. The front protector may make the bed more rigid. The tailgate protector would keep me from scratching the tailgate with my ramps. Deflecta-Shield has a web site with some good pictures of their products.
Maybe this helps.
