Got rid of my 2003 extended cab 4.8 LS with flaky gauges, 2007 has 5.3 with LT2 package.

Any suggestions between the bedliner and the bed mat? Is the Cargo management a plus or minus, as I put my bicycles in the back when going to races.

Will post my mileage results, I got 19-21 with my 2003. Best was 23 going to LA, cruise control at 63 with traffic.

 

Definetly a spray on bedliner, like Rhino Lining.That is sufficent. Cargo Management? They have Active fuel Management. I have the 6.0 and get 14/17.

I would recommend theRhino Lining. I had my 03' done when it was new and the lining still looks brand new today. I've hauled all kinds of things with no worries. This stuff is tough. It's easy to clean just wash out with a water hose and that's it. I bet it will help the resale value as well.
