how's eveybody? Great! I've been getting this banging feeling when I slow down and give gas again.Like when going around a corner,or like when the light turns green before a full stop.It feels like it's in the back.I just want to see what you guy's think before I go to the dealer. THANKS.

 

Might want to check out the spare tire. If it were a little loose it could make the sound/feeling your describing.

 

Shouldn't be loose on that new of a truck, but the tailgate may be in need of adjustment.

Sounds like the feared driveshaft/transmission clunk to me. I'm not sure what causes it but I have read a lot of threads on this topic. My truck does it also, and I believe there is a TSB on it. Check all of your U-joints for looseness.
