Hey scotty I have a 2008 Tahoe, 210,000 miles  original owner and it just recently began to have a slight shudder/vibration when at idle. 
move kept up on all the maintenance oil every 5, transmission, transfer case, and differential every 30k. Any ideas? other than that it drives and handles as smooth as could be.

Start with checking all your engine & transmission mounts.

Also check specifically for loose, cracked or disconnected vacuum lines, or a dirty EGR valve.
