I couldn't have had very much, I only drove loaded a couple times. Be persistent and remember the line: "I didn't feel safe driving with even a small load".
If you just bought the truck from this dealer I would hope they would be very interested in providing you excellent service (have you got the survey yet?).
Again, be firm but respectful and it'll go a long way. I wouldn't expect any company to blindly replace parts, the inspection is part of the process. Those that have related stories of "I told them about the TSB and they ordered the parts right then" are the exception... not the norm.
I am shocked it was so easy.
So why did I not call them in the first place? Well, they are 4x the distance from my house as the dealer I called.
I will let you all know if it all works as easy as the service manager stated. Also thanks for the comments, I learned a lot from this thread.
