I have a windshield sun screen on my 2004 Georgetown by Prompt RV Sunscreens in Florida. Very impressed by the ease of installation, no need to fasten domes to the body and it doesn't move even in the worst winds in Texas.
Check out their website at www.rvscreen.com
I added Power Visors from Carefree of Colorado. Bought them through Camping World. I added them mostly because the visors that come with the coach are just about useless. I don't know how they expect you to adjust them while driving down the road unless your passenger does it for you. Worse yet it always seems that the sun is above the bar and still hits right in the eyes. I bought the remote control so I can set it wherever I want it and can use it in the complete down position for blocking out the light.
I also have a windshield sun screen from rvsunscreen and very happy with it. It fastens with suction cups-no need for snaps or velcro. I was reluctant to put snap holes in my 2004 Georgetown. Goes on in seconds from the ground-no ladder needed.
we have drop down electric ones l
but they didnt stop the heat so we made one that snaps up and has the foil/bubble wrap stuff and neat fabric one side has deer and the other has fish

When you order rvsunscreen they ask what motorhome you have so they custom fit it for you. Mine fits extremely well and tight to the glass-had it on all winter in the wind at Bullhead City and had no problems with the screen or suctioncups staying tight.
