I'm somewhat of a stickler for getting good mud flaps, etc. to protect my truck, trailer, camper or whatever else I might have in tow.
On my trucks I have Duraflap mud flaps behind both the front and rear wheels. I even have a custom, stainless weight in the rear mudflats with a jumping salmon design - they also make these mud flaps with a variety of designs, if person is interested.
I also have a Triton trailer for my Polaris Ranger (I see you've also got a Triton), and I have an air dam across the front of it which provides some further protection against road debris. My Triton is a somewhat bigger model, which Triton made an airdam for, but I don't know what other models they have them available for.
I also used to have a couple Enkay adjustable mud flaps (similar to the Roadwings you've pictured) for when I had travel trailers. Enkay's are the Rock Tamers. One nice feature of the Enkay's in that they are adjustable in, out and can be angled front or rear, to best fit your specific tow vehicle. I see that Weathertech also makes mud flaps now that look similar to the Roadwings in your picture, but I haven't actually seen or looked into them to know how they would work.
