Nice truck. Looks like an electric bed cover like my '14 came with. I love the convenience of a push button. I don't think I would flush the tranny. We did our Lexus years ago and it lasted about 2 weeks before we had to rebuild it. When I purchased my F150, the transmission shop told me not to change the fluid at 122K. My Raptor was bought with 136K, but had several changes done before I bought it, according to the carfax. I'll change it when the next interval is due. Good luck with your truck.
