Just past 4k on miles.. mpg is not what they say it is, but I didn't buy it for that reason only. Love the air suspension and the 33 gal tank. On the highway this thing is very responsive and smooth. City it's quiet outside the tread on the aggressive tires.
So far no issues on the engine, or the truck itself. I love the map display on the speedo. The different modes are really nice, sport, off-road, snow, and tow..
So glad to see another one who is performing well... as of now. I am a worry wart and need more positive stories.
