Roughly how much would you say you spent on the liner for your rhino?Talk to the guy at Sound Deadening Materials for Noise Reduction from Second Skin he told me about vibrations and how to get rid of them. I did my whole rhino and it is much better. Bedliner material is not designed to get rid of vibration only protect you bed. They make a material to get rid of the vibration of your bed that worked great for me. This guy is very knowlegeable about noise reduction. I would call him.
