left side further forward showing vertical rib between what would be the kitchen window and the large left side window. two upper 3" wide horizontal ribs were added by up-fitter to accommodate this transmodes use as a mobile electrical equipment (Furnas Electric) showroom Mobile sales office. lowest 3.5" rib is the beltline


I have some suspicion that the 3" horz ribs MAY have been installed by GMC and were relocated down by up-fitter. There is a cryptic build code on the build sticker in the glove box that I don't know what it means.
