+1Love the backup camera zoom for hooking up to a trailer by the way.

I think the dual exhaust looks great but really sucks when your hooking up your trailer to a running truck. At that point you are sucking in all the exhaust fumes... Yes, you could turn the truck off while hooking up, unless your DW and children are inside sheltering from rain, heat or cold...
Something is totally off there.My 5.7 non etorque only got 6.5 mpg pulling a 3,700 lb enclosed v nose trailer! I would get just about double with my old 07 Duramax. Disappointed!
