Hello from Central Texas area. Picked up Quad Cab Laramie 4x4 with EcoDiesel and Air Suspension last Monday. It is two tone White and Silver with Black interior and has the 8.4 display without the Navigation. Avg mpg is 24.5 right now mostly stop and go traffic. Had dealer ad the Electronic Brake Controller and software update. Installed Rhino spray-in bedliner and windows tinted (not thru dealer). Tried to upload pics but keeps saying doesn't recognize .jpg format. What's up with that?
