By under load I mean I am accelerating or moving under power of the engine, putting tension on the driveline. When I push in the clutch and I am freewheeling/coasting is when I feel the vibration start. As soon as I release the clutch and start to accelerate the vibration stops and the ride smooths out. No trailer or anything in the bed.
