This has been discuss a little but not in much detail.
I talked to knapheide
today and they say the reason they will not upfit the tundra is because Toyota will not allow it.
I decided to call Toyota (Phone: 800-331-4331) to let them know that they are missing the boat.
Why build a heavy 1/2 ton if you do not allow some sort of upfitting. The truck will do it, best truck in the class and it would be great. As it stands they over built a city pick up.
If you know someone that will put on a lanscape bed with a dovetail let me know.
