I've been driving a Jeep Liberty for a couple years as my daily driver (and I've hated virtually every minute of it). Long story short, a 2105 Silverado crew cab followed me home this weekend (just in time for fireworks, my wife and I are both licensed "Exhibitors Assistants" (pyro techs) for professional shows). Within 12 hours of signing paperwork, we were hauling stuff around the site and driving through in 6" of soft muddy grass (oops). It's a truck, right?

I need a front license plate bracket. My truck came from out of state and what they gave me requires drilling holes in the bumper (I'd rather not due to rust concerns). Is there anything like the SLP bracket for the 4th gens that fits the new trucks?

I'm looking for a roll up (semi rigid/secure) tonneau cover.

Throttle response sucks, so I'm going to need a programmer to fix the throttle feel. I'm not worried about power (it makes enough for now), but the throttle could use some help. It opens really slow and then you start stabbing it to get it to move. I'm not a fan.

Has anybody fixed any of these issues? Tips, tricks or recommended parts?

Nice truck! Did you get the HID lights? I didn't buy the LTZ, so I didn't get the HIDs on mine. (IMG:http://www.frrax.com/rrforum/style_emoticons/default/sad.gif) And I was ok without leather (though I've had leather in most of my recent cars, so I could go either way).

I've done some digging and I also found that these had the 9.5" axle in them. It's not as bomb proof as the 11.5 in my last truck, but it should be a lot more efficient. And the 6L80 transmission has two overdrive gears (I wasn't aware of that either).

What gears did you get in yours?

I just took mine on a 900 mile road trip (from Columbus to the Summit Point Raceway area) and I averaged 18.5 mpg for the entire trip (city, highway, stuck in traffic and all). We were seeing up to 21.5 average (on the rolling 50 mile average) in the mountains with the cruise set on 77-80 mph (with lots of 6-8% grades). I can't complain about that at all.

It requires "Dexos" rated oil (0-20) and it holds 8.5 quarts (seriously). They claim GM can tell if you run non Dexos rated oil and the engine fails. I was not aware of the new Dexos spec, but the green cap Mobil 1 0-20 has the Dexos logo on it.

Then keep the Dexos oil in it! It seems the current crop of LS3/L99s have weak rocker trunions, which break, letting the needle bearings drop into the engine. Sometimes it's caught as a tapping noise in the valvetrain, sometimes it's caught on engine teardown after the car is towed into the dealership after loosing power.

Some are bringing their brand new Chevy SSs home to start engine mods, and discover needle bearings laying in the head when they pull the valve covers. (IMG:http://www.frrax.com/rrforum/style_emoticons/default/unsure.gif)

Heck, the engine in our '12 Caprice had a cam and lifter replacement after a lifter failure, but that's associated with the AFM system.
