this isn't exactly the "import tuner market" ie: honda civics, acura integras, wrx's....
Tundra's aren't known for their underbody neon's, huge wings, and fancy stereo's, and then their 100 car meet up's
even with that, you have to put a crap ton of money into your ride, before getting a sponsor to look at you, and at that point, you have already bought their products.
I say, see if Nestah will give you a free antenna, Big Tundra hook you up on the full monty, Coachbuilder make you up some shackles and roof rack, DirtyDeeds get you a full exhaust, GCOP for some HIDs, and Texasranger hook you up with his cooling fans...
then you'd basically be a TundraTalk sponsored truck. Score!
