A truck/jumbo sized windshield sun shade fits perfectly behind the curtains in in the cab over. The curtain rod holds it up and in place no need to tape it in place.
Drops the temps in the cab over dramatically.
It's the thickness of these that really helps keep the heat out along with reflecting it. About 200 times better than the limo tint.
14.00 Walmart and if you want to be creative they have dozens of different colored and pictured ones as well as the diamond plate silver.
