Love the truck, wish it actually could get in the MPG rates that the window sticker had... but I didn't buy it for gas mileage. I'm averaging around 13- 14 MPG mixed driving. Other than that, it's a great pickup, plenty of power. A side note: I got sat. radio free for a year, neat service. I'm hooked.
Exterior appearance and stance. I've got the BigHorn pkg which includes the 20" rims, and they really look sharp.
Make the storage under rear seat more configurable instead of just a couple of storage "wells". Use a bit higher grade plastic for the glove box and drink holders, they feel really cheap... and they shouldn't on a 30K+ vehicle
