Just some random updates and feedback:
I just hit 500 miles on my odometer and got the "28% DEF" system alert. Just another reminder to check every fluid, lug nut and anything else the dealers can screw up. I live in MA and we just got a good 16-18 inches of snow where I live and I was certainly impressed with the 4wd system compared to my LBZ. The tie rods appear beefier than previous models and the rocker panels are coated with some kind of hard, smooth, yet textured coating. Coming from a 26 to a 36 gallon tank is nice, and I averaged around 21mpg highway and 14-16 in town.
The HID projector headlights are impressive, with a nice neutral color that appears to be between 4300-5000k. The cut off is not extremely drastic like some projectors and the high beams throw as far as you can see but apparently the HDs models aren't worthy of the 1/2 ton LED fog lights, even the Denali. I swapped in a mild set of LEDs for the 5202 halogens that were useless, until I put in something like the Morimoto LED fog housings with the sharp, adjustable cutoff and more flood. I also put 3x800 lumen chip sets in the cargo/3rd brake light to compliment the mirror lights and bed rail LED lighting. Because I opted for the factory sprayed bedliner, the cargo tie downs they provide are useless because they simply spray over the inserts for them.
After test driving an LML, the L5P just feels light on its toes, and throttle response felt great. It dwarfs my leveled LBZ on 305/50r20s side by side and I personally like the drivers view with the more squared off front and hood scoop.
Question for those of you who may have underseat storage for the back seats (which might as well not exist considering they don't have heat/AC vents, radio controls, headphone jacks, or console drop down cup holders in a damn near $70k truck) I didn't get the factory underseat storage and I'm looking at either DU-HA, Husky (looks kind of cheap), or the GM factory version. Also wanted to go with a Weathertech type of mat setup if anyone had recommendations that'd be great!
If anyone has any questions, I'll do my best to answer them!
