Windshield Sun Shades, Car Window Shades and Car Window Covers by HeatShield: The Original Windshield Sun Shade
I got a set for my 579 door windows and windshield. they work great, keeping the cold out in the winter and the heat out in the summer. They are made to fit, and are much better than what you get at the truck stops.

 

You can buy a 10 foot roll of reflectix, the reflective sheet used to make windshield sunblocks, at Home Depot and Lowes and cut out a custom version for yourself. Costs $10-15.

When I had rental trucks, I just bought 3 black bath towels from Walmart for total of $10-15 and used that as a windshield curtain. I could use a Love's card to force the towel into the gap between the top of factory sun visors and the bottom of the overhead storage boxes. Or you can wedge the towel into the rubber windshield gasket on some truck.

There are many ways to skin a cat. Not everything has to come with a matching factory logo or be sold in a truck stop to be used in the truck.
