27 Jan 2009, a closing update to my previous posts:

To my satisfaction the tailgate has been replaced with what is purported to be the latest tailgate for my vehicle. I am very satisfied even though it was a long time coming.

I was patient and willingly waited as I did not want to rush the dealer and be given a duplicate tailgate or just have mine repaired. I had accidentally punctured the outer skin of the tailgate (boat trailer coupling struck it) just above the bumper and that was determined to have "compromised" the integrity of the tailgate itself. I agreed with that posture and did not argue the point. It was well made I suppose. In any event after the Toyota Rep inspected the vehicle and we talked about the issues I had seen here on the forum he believed that the tailgate could not be honestly replaced under warranty but that he would submit it for a goodwill repair, which resulted in the tailgate replacement. They even replace the top protector for the tailgate which I did not expect but surely appreciated.

To say the least I am totally satisfied now and my faith in Toyota to stand by there "Tuf Truck" motto is restored. Tomorrow morning the Tundra will be pulling my travel trailer to the Eel and Smith Rivers for some Stealhead fishing.

Life is Good,
Jim

PS: thanks to all on the forum for your support and tips.
