Showcase Miniatures now has their Peterbilt 362 COE semi-tractors available in both day cab and sleeper configurations. Both models feature resin cabs and stainless steel grilles and mirrors.
Also, many of their other truck kits now have resin cabs and stainless steel grilles and mirrors as well. You can see a photo of their KW T800 dump truck with the new cab on the N Scale Vehicle Association's Industry News page.
