Happy New Year, everybody!
I have a Freightliner Cascadia that I pull a side dump trailer with. I have a pretty useless quarter fender in front of my pusher axle and individual fenders on my pusher axle but nothing else for fenders on my drives. I have some mud flaps hanging on the front of my trailer that catch most of the stuff coming off of my drives by not all of it. Shattered the left rear window of my daycab Cascadia in November and did it again two days ago. I do almost all of my driving on gravel roads and my drive axles keep throwing rocks. At $350 per window plus the cost of losing a day of billable labor... I need to do something to stop this.
Straight to the point, I'm getting fenders. I prefer the look of the full over-the-top fenders pictured below. I only pull the side dump right now but will likely expand into doing some low-boy/detach equipment hauling at some point. But... from the places that I've called around to, the single fenders similar to the ones in the second picture are cheaper. I'm not crazy about how those look but I'm more about the bottom line and functionality than looks.
The only thing that I can think of to justify spending more money for the fenders that I want is that the single ones could be damaged a little easier in off road applications like what I'm doing. Not only am I primarily driving on gravel roads but I'm driving in and out of rough jobsites and into corn/bean fields in Nebraska. I'm not very nice to this truck at all.
Does anyone have any opinion about what style is better, one way or another. I'm especially interested in which style does a better job of keeping rocks on the ground and not flying through my back windows.
As always, any input is greatly appreciated!!

Have you considered a way to keep the rocks from the window? Headache rack, wire mesh, or plexiglass? Less likely to be a problem.
I haven’t tried the long plastic, but I hate trying to keep the little singles on the truck… in an off-road application it can be done and they are more likely to keep the rocks contained than the one piece.
I would recommend the one piece that the center goes low like the individuals as it increases rigidity and mounting points.
(This is from a drivers not an owners perspective)The_SnowMan710 Thanks this. -
One piece fender does a better job IMHO.
We run them both and the individual feners always seem loose at mount and then would need to be repositioned and redrilled into the fender itself.
Look hokey and soon becomes ineffective with each remount.
I found the full units to be better despite the flexbeastr123 and The_SnowMan710 Thank this. -
I forgot to mention that a headache rack isn't an option... or at least an easy one... right now. I have my hydraulic tank on the back so I'd have to move the tank or put the headache rack in a dumb spot. Here are some pictures of my truck so you can see what I'm kinda talking about. These first two pictures are with the old stubby little mud flaps on the front of the trailer. They didn't do much.
Here's my first shattered window. Man, when that thing goes, it sure does send you from zero to mad in about 0.002 seconds.
This is the second time I've taped up my window. Thanks to a local O'Reilly's for the free boxes.
Here's how my truck routinely looks like. She's not a beauty queen, not by any means. But, I got into this to make money not win beauty pageants. These last two pictures have my new, long mud flaps on the front of the trailer. They worked better but obviously not the cure-all. You can all see the normal terrain that I'm driving on. That's the thing that I think it would be better to have the set of fenders that are straight across the top of the drives rather than the individual ones that go over each set of duals. I feel like the individual dual fenders would get tore up pretty easily and I would likely be replacing them frequently.

I would just go with some quarter fenders in front of the drives and maybe hang a little longer flap from the trailer.. easiest and pretty effective.
The individual fenders can be a pain as can the long single. Keeping them mounted and being in the way for maintenance and different trailers.The_SnowMan710 Thanks this. -
Real Wheels Rear Window Guards For Freightliner Cascadia
I would probably just get these covers. On my blue truck I ran half fenders with some pretty beefy blind mount brackets and the brackets would still crack. The poly fenders are lighter than stainless but those would still vibrate on gravel roads. And when they break then you have to ratchet strap them to your frame until you get home to take them off.The_SnowMan710 Thanks this. -
I did order a set of those but they were so flimsy that I decided to return them. In fact, one was already bent from shipping. That and they don't swing out to clean the windows. I know that probably comes across as a pretty stupid thing to say after posting pictures of my routinely filthy truck but I do like to see out of my windows.
I did find these online and thinking about trying it. Either that or get some double sided tape and some plexiglass and put a homemade version over top of my glass. When the plexiglass eventually yellows then I'll peel it off and get new ones again. I intend on getting fenders regardless of what I do for window guards

After seeing what you are working with, I second the quarter fender in front of the drives with the longer flaps on the trailer.
Those plexi covers should stop what ever gets through after that. But watch that they have a big enough gap behind them to not break the window anyway when they flex.
When I was thinking of a plexiglass stopper, I was thinking along the lines of what you would see on the back of a highway maintenance mower. Just a big sheet spaced away from the cab just far enough to clean it or as a glass replacement. As for the mesh it was a similar thought about the spacing, with a similar mesh to what I have seen in pictures of the lower portion of Australian coe windshields. https://external-content.duckduckgo...4dca1b0456558e515a4f4a21bb64057b9a&ipo=imagesLast edited: Jan 2, 2026 at 12:18 AM

I get what you're saying. If worse comes to worse, up just build my own thing like what's in this picture. I have the means it's just finding the time.
