Get them warm (sun, heat gun, hair dryer, etc) and peel them off. Use 3M Adhesive remover to remove any residual adhesive. Super easy to do with no damage. Just remember that you are peeling off $100-bills. It is stupid to think the bedside deals are $1000.
Local dealer quoted me $600 for the bedside graphics themselves. I eventually changed my mind and decided to leave them off.
If the truck came with them, I’d leave them on
