I just bought the base model SLT with the stereo package. I've been adding to it ever since. Paid 26k for the truck. I've put about 6-8k into it so far. Next step will probably be finding some tires and rims. Moto Metals are lookin nice to me right now.

 

Just bought 2010 slt/bighorn crew cablove it so far. 20"wheels. Going tomorrow to get line-x spray in. Im gradually adding stuff. Looked at exhaust, not sure on brand,etc.

 

I wish that manufacturers would build a base model and then provide "plug 'n play" accessories as dealer or aftermarket add ons:

Audio options
Wheel/tire options
Bumper options
Exhaust options.
Console options
Etc.
