What year van? My 1991 and 2004 only had residential carpet installed from Roadtrek. You should be able to remove the seats, yank out the carpet, and use it as templates.
I found a vendor on ebay (stock_interiors) that sells formed carpet for cars, trucks, and vans. For the vans, they sell a carpet for the passenger area.
