Intermittent vibration on the highway - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Today, I made a 200 mile trip in my truck and every 10 minutes or so, I would feel a vibration going through the truck that was visually moving things in the cab. It didnt really matter what rpm I was going. I stopped to inspect the truck under the hood and looked at the tires and everything checked out. I even gave the two driveshafts a tug to check for worn U joints. I cant narrow it down. I dont think its in the driveline because its not constant and rpm has no bearing on the vibration. Could it be bad shocks? What do yall think?
