I'm wondering if anyone here has put the RBP RX-1 3 Rung side steps on a 2012 chevy silverado 1500. I have the extended cab with a 6.5 foot bed. I emailed RBP to see if they can tell me, but I'd like to hear from someone that has done it if possible. Everything on the RBP website says they only fit up to 2011. Thanks for any info!
