I going to disagree. I think Rt will have a Transit Van conversion to show before the end of the year. Plus, your forgetting about all the people like me who need a gasser, because of the generator. I, and other people living in the west, need to run the AC, also there is a lot people who just want a gas van.
I think Rt and others will be very happy not having to cut out a roof, and installing a fiberglass one. That has to save a lot of time and money, and issues with leaks.
I see the Chevy van going the way of the dinosaurs.
