I had a circumstance where I needed my tailgate lights at night(one of my negatives of the truck)while I had 7āx4āx22ā locker in the bed. Propped it on the tailgate with rubber mat for protection. Ratchet straps to secure from d-ring and L-track. Use D-ring by cab to keep from sliding away...
This vibration has been an issue since day one, though Iāve had no audible bass boom. The mirror āticklesā my eye when Iām looking forward (driving) and draws my attention.
Have a service appointment at the end of the month, with this included, should be interesting.
