Am I the only one with a LMM (2010, 20,000 miles) that, every time I start cold in the morning the whole truck interior sounds like a morracca? I tried getting the dealer to look at it, but no luck. Once things warm up inside it stops. Anyone else have this?

A) You need to change your signature.
2) Mine don't do that.
iii) Is it just the doors, or is it in the steering wheel/ center console/ etc?
IV) Are you running aftermarket goodies (running boards, exhaust, lift, etc)?
e) Have you lubed the door seals (with silicone, of course)?
