Try a different dealer. A few here have had it done successfully on 2009s.
Even with the TSB the truck will bottom out on occasion w/ TSB!
I had 800Lbs of shingles in my truck over the weekend, It did sit awful low, But didn't bottom out like it did with 720Lbs of plaster in the back before the TSB.
Oh, white bread, I have a 2009, And had the TSB done. the dealer did come at me first and say that Toyota said it has been updated. When I mentioned why it only had 3 leaf springs. and the TSB calls for four leaf springs. also that it bottomed out with only 750Lbs i it. the dealer agreed with my tottal and said they will find some way to do it.
