Pulling up an old topic. I am buying a 2010 GMC Sierra 6.2 with DPN(power, heated w/turn signal camper mirrors) I do not want them. I want to go back to standard mirrors. Do I need to go with DL3 (power, heated w/turn) to avoid any issues or can I go back with DL8 to go cheap? My truck doe shave RPO AN3...and if anyone has DL3s and wants DPNs, i'll trade straight up
