Most threads on here are just complaints and negativity which is OK, but just to be different this one is only for the thing you really like about your 19+ trucks.
Sooo....
1. Love the power of the new 5.3, having come from a 2005 the difference is huge
2. Love all the extra room inside the cab
3. The family loves that it has heated rear seats
4. The multi pro tail gate I didn't think I would ever use, but now wouldn't want to go without it
5. The increased fuel mileage is great (about 5 mpg better than the 05)
I could go on but I'll leave some for everybody else?
