Correct. Not avail on WT or base Sierra. Standard with the SLE/SLT and LT/LTZ packages. Locking tailgate is standard on all versions.

Ordering guide shows ez lift as standard on sle and slt.

I was in the frame plant when the '04's were in production. I can guarantee they were wax dipped.

The rims in the pic are only available for 20's

Maybe I'm confusing it with the various mpg screens it had.

It was on the SLT double cab I test drove.

Take one for a test run and make the comparison the same way you check your current ride.

It probably also depends on the axle ratio of the truck.

On my 2500, the sensors don't like it when there is a ball mount in the trailer hitch.

Probably only the 2500/3500's.

The difference is as likely to be differences in how fuel the tank is on the 2 refills.

For those that are interested the diesels have the 'fast idle' and also an 'elevated idle'. Elevated Idle The engine has a cold temperature high idle feature which elevates the engine idle speed from base idle to 1050 rpm for pickup models or 1200 rpm for van models when outside temperatures are below 0°C (32°F), and the engine coolant temperature is below 65°C (150°F). This feature enhances heater performance by raising the engine coolant temperature faster. This feature can be turned on or off using the DIC buttons. If the vehicle is not equipped with DIC buttons, do the following to turn this feature on or off: 1. Turn the ignition to ON/RUN, with the vehicle off. 2. Press the accelerator pedal to the floor and hold while quickly pressing the brake pedal three times in less than eight seconds. 3. Release the accelerator pedal and start the engine. When the engine is started, it will slowly ramp up to the high idle speed after a delay of a few seconds up to approximately two minutes. For this method to work properly there must be no throttle or brake pedal faults. The engine idle speed will return to normal once the following conditions are met: Once engine coolant temperature reaches 65°C (150°F). Air intake temperature reaches0°C (32°F). The high idle speed will be temporarily interrupted and the engine speed will return to normal if any of the following conditions ccur: The brake pedal is applied. The accelerator pedal is pressed. The transmission is shifted out of P (Park) or N (Neutral). Vehicle speed is detected. Once these inputs are removed, the engine idle speed will slowly ramp back up to high idle after the normal delay, if the conditions for engine coolant temperature and air intake temperature are still met.
