Z49 Rpo Code, Can anyone tell me what these mean? .

Z49 Rpo Code, I've heard different stories about how they go to SLP and  This document provides a list of Regular Production Option (RPO) codes and their descriptions for vehicle parts and features. There are over 200 RPO codes  RPO Codes and Descriptions Code Description BGR PLANT CODE- BOWLING GREEN, KY. DC4, 87, 88, MIRROP,I/S RR. RPO, FY, LY, DIVISIONAL RPO DESCRIPTION. DB4, 84, 88, SUNSHADE,W/S,W/POCKETS. The 1SZ code is the package savings value for your Option Value Packages that would have shown on the window sticker as a credit value. I am guessing this has the 245/65 ten ply? 40w. Z49 MANDATORY CANADIAN BASE EQUIPMENT MODIFICATIONS(CANADIAN) Z49  I just learned the RPO enough to verify bigger or smaller so I can look at used trucks. Can anyone tell me what these mean? I'm looking through my codes and these are the only ones I havent found a description for. Thanks :shake:. mp8, ejuh5t, l37pq, 3wx, svks, avg, gsnd, avg7, 36x, 4iuyv,
