I bought something like this HD poly mesh tarp, only smaller, ours is 6' by 8'. The one we bought was black and the mesh part was fairly thick to begin with.
Mesh Tarp Towed Nose CoverWe fold it along the 6 foot axis to make it 4' by 6' wide for extra thickness. It's got brass grommets every 2 feet, and we secure it to the nose of our Wrangler using bungee cords.
I place one 6' edge down front covering the fog lamps (will be just above the tow bar knuckles and connections) and secure it around and underneath the wheel wells with one set of bungee cords. Then we pull/stretch the opposite 6' edge up and over the hood, and use some more bungee cords to secure it to the mirrors, or wherever else I can, to keep it secure when underway.
Caveat: I haven't tested it in actual towing yet, as we're between motorhomes, but have installed it on the Jeep, and driven at highway speeds with it in place, and it does stay put. You can actually see the Wrangler lights through the mesh, even when folded in half, although I wouldn't use it at night.
Sorry, I don't have any pics. I'm fairly confident it will give us some additional coverage of the nose, grill, and the lights. It probably won't protect the windshield, unless we unfold it, and use it at it's full coverage area. Maybe in the future, if necessary. It's all experimental at this point.
Total cost, C$45 for the tarp, and a few more dollars for the bungee cords.
EDIT: Should have mentioned, we pulled our Wrangler behind a WGO Sunstar over 4600 miles last October with no problems, and we had neither rear wheel mud flaps, or a full width rear skirt. No damage problems, except the road dirt and grime on the face of the Jeep and the butt of the Sunstar.
