Suburban Seems To Vibrate A Lot

[2004Suburban]

Hello,

I recently purchased a 2004 Suburban and notice that the entire vehicle vibrates when sitting in traffic. It is not stalling or running rough, it just seems to vibrate more than at other times when stopped in traffic, in or out of park. I can feel it through the steering wheel and the brake pedal. Is this normal for these trucks?

Thanks

isn't this a double post?
