Sterling Bath Products (a division of Kohler) can make a custom shower door in virtually any size and configuration you need. They are available with your choice of frame colors and glass designs. They're a bit pricey, but not as expensive as you might pay if you bought it from Jayco. You can price/order one at the Kitchen & Bath Design Center at Home Depot.
