This GMC chassis-series nameplate belonged to the brand’s heavy-duty van/chassis family used for commercial upfits, step vans, and motorhome-style applications rather than as a conventional retail passenger model. The series appears in GM and aftermarket service references for the 1992–1996 model years, placing it in the final era of GM’s P-series forward-control platform before the company shifted its full-size van business toward newer architectures. In practice, the chassis was part of a working-truck lineup that supported specialized body builders and fleet operators, with hardware and brake applications documented across the run in parts and service catalogs.
The nameplate is best understood as a derivative of GM’s long-running P-series truck/chassis family, which carried a wide range of incomplete-vehicle and commercial uses. By the mid-1990s, GM was transitioning its van and commercial coverage toward the Savana/Express-era products, and this chassis designation disappeared after the 1996 model year. Because it was a distinct, limited production run with no verified revival under the same nameplate, it should be treated as a single continuous historical period from 1992 through 1996.
