Sorry to resurrect an old thread but... I was wandering if anyone can tell me if a rear panel windjammer stops rain water from being sucked in during higher speed riding on rainy days. On the farm we use the pioneer in all conditions. The dust doesn't bother me much but I could do without getting hit in the back with water on rainy days when traveling between pastures/ fields. I have the seizmik vented hard coat windshield and an oem hard roof, the windshield vents don't help with the suction.
I have the same Seizmik vented windshield and roof and I know what you're saying.
My poor-boyed rear mesh helps with dust and stops rain and snow. There are also sites that sell these.
I bought a dump truck cover ($22), a brass grommet kit ($17), upholstery needle and thread kit ($15), and a handfull of ball bungee cords ($11).
Cut it, hand stitched it, and put in the grommets. I used the fiberglass rod from a broken whip flag to thread along the bottom.
If I don't want it down, I can roll it up and secure it up with the ball bungees. I generally load and unload the bed through a side door anyway, so I leave it down most of the time. Your farm use may need to tailgate load more, but you can probably get away with fewer bungees. Frankly, I put three down each side because I Interstate tow my machine a lot and need to deal with 80 mph wind.
Side note: the dump truck cover had enough leftover mesh that I made front and back overhead compartments for gear. I used matching grommets top and bottom, closed with ball bungees, and stitched small ratchet straps to the mesh - wrapped the straps around the roll cage and they hold tight up under the roof. The nice thing is I can leave a lot of stuff up there and it won't get wet even when I wash the rig.
