Does anyone else have a hermonic vibration at 25-30 mph with 10% throttle??

1100 miles. Yes. Also slight vibration at around 55 - 70 mph. Driving myself crazy trying to remember if I felt tis when I picked up truck or if I have developed a phobia after reading all fo these posts. Seems likes rpm's are typically around 2500 when I feel this subtle vibration in the gas pedal. Doesn't particularly bother me. Just don't want to be doing damage to the drivetrain or engine.
