2013 Chevy truck vibration?
Some time ago, I recall reading about an issue with some kind of frame vibration in new trucks -- can't remember if it was the 2013 GM or not. I know a few guys on here had a problem with something...

I know a few guys on here had a problem with something - and dealer could not figure it out ... several actually. It's sticking in my brain, but I can quite grab it ...
Anyone recall it - and the fix result ... Thanks ...
Or point me to that tread - those threads?
It's called frame beaming and GM has put out a service bulletin, PIT3009 on it. My 2009 2500HD had it and my dealer fixed it even though it wasn't part of the recall.
#PIT3009L: Suspension Vibration Or Frame Beaming At 40-60 MPH (64-80 KM/H) - keywords front rear shake shock spring tire - (Dec 3, 2009)
Subject: Suspension Vibration or Frame Beaming at 40-60 mph (64 - 80 km/h)
Models: 1999-2009 Chevrolet Silverado and Silverado Classic

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern:
Beam shake vibration is usually felt in the seat and occurring at speeds between 40-50 mph (64 - 80 km/h). Hertz readings using an EVA tool are normally between 8-24 Hz. This condition is most common on extended cab and crew cab models but has also been noted in other models.
Recommendation/Instructions:
The severity of beam shake may vary from vehicle to vehicle. To determine if the concern is beam shake, please perform the following:
•Test drive vehicle to confirm the condition. A beam shake condition will usually respond to concrete type pavements more than asphalt, so the vehicle should be driven over both surfaces if possible.
•Place 200-500 pounds in the pickup bed between the closed tailgate and the wheel wells. A beaming condition should dissipate.
Note: Tires with excessive Radial Force Variation (RFV) or out-of-roundness can intensify the frame beaming concern. The following radial force variation numbers should be used as a guide:
P-Metric tires (2wd 1500)
12 lbs or less
