GM did actually make a handful of class a motorhome I can think of a few 90s models. But GM has not made a motorhome since then. Most class A motorhome manufacturers use headlights from car brands so that when it comes time to replace headlights they can easily be obtained through various sources instead of having to get them from the RV manufacturer. Especially if the RV model in question is no longer being manufactured. Tiffin likes to use Chevy headlights. Several year models of the phaeton class A diesel pusher use GMT900 Tahoe headlights. A few years of the allegro bus gas class a use gmt900 Silverado lights. And if I remember right one of the tiffin diesel pusher models used 2003-2006 Silverado tail lights on the back end. Several early 2000s models made by the motorhome company national, used GMT800 Tahoe headlights and corner lights in their front end setup. Somewhere around 2014 or 2015 I think, one of the big holiday rambler diesel pushers, I think it was the HR Navigator used GMT800 Escalade headlights.
