Picked up my 2015 double cab about a month and a half ago, definitely my favorite color on these trucks. I live down a dirt road and I've never seen a color hide dirt this well, the back of the truck can be completely covered with dust but there's no way of knowing until you are standing a foot away and really looking for it. The iridium metallic truck we have turns two-tone in the same conditions, dusty on bottom and iridium on top. Unfortunate that they don't offer this color anymore but I'm sure glad I snagged one.

In the spirit of troubleshooting, are any of you guys able to hear this noise in park or neutral when you give the engine some gradual RPM? I'm experiencing something that sounds pretty similar to this noise in my 2015 Silverado (5.3L 13k miles), but it's only when I'm in drive going down the road, and only when there is slight throttle being applied (may continue under more throttle but engine noise likely drowns it out). No noise when coasting or when revving in park. Severity fluctuates day by day and sometimes I don't hear it at all. The 2014 Sierra (5.3L ~40k miles) doesn't do anything similar. I guess I'll try giving it some gradual RPMs in neutral or park after the engine is warm, can't really remember if this sound presents itself immediately when the engine is cold or not. Similar to some others in this thread the noise seems to be coming from the driver's side footwell, or at least the driver's side of the vehicle. I'm just stumped at the fact that it only wants to make the noise when throttle is being applied, and so far as I know only when the vehicle is in drive and underway. I'll get it looked at soon, and hopefully will have some useful info to report back.
