During the four plus years that I have been fooling around with the RR trk I have encountered four other examples of an extended cab pickup. Most of the trucks I have found were on-line, however, there was one for sale at the LA Roadster Show in 2017. A couple that I have seen were a little funky looking because they were not on a long wheel base chassis which meant that the bed was very short with the rear tires almost touching the rear of the cab. The bed on my truck is a conventional GM 6' bed.The rear side windows were not the suburban style like my truck, they were more like square camper windows with aluminum frames.Wm
