Saw this today at my local Costco... all the way from CA...
I haven't had an issue regarding mudflaps here in Texas yet, but I understand the locals in Moab require mudflaps.
Roadwing by ROADMASTER...
I don't think I'd pay $186 + $36 S&H for them, but... certainly gives me an idea. Luckily I opted for the receiver hitch. Sorry I didn't get a closeup of how it connects, but appeared to slip over a hitch. I believe I'll measure one of my hitches and purchase a short piece of thick walled square tubing to slide over it, drill a hole on each side to tap and/or weld nuts on for set screws/bolts. Build out from there. Believe I'll weld a 1' section to the piece over the hitch and drill it for bolts such that I have the two wings bolt to it. That way I can disassemble and store. Maybe wingnuts to hold the flaps.
RoadWing’s “anti-sail” design keeps the mud flaps down, where they can stay on the job — double-bolt attachment points hold the system in place, as well as level on the bevel, and grooved interior channels deflect rocks, gravel and road debris down and away from your towed vehicle or trailer. The RoadWing slides over your ball mount or tow bar stinger, and is easily attached with set bolts, or just as easily detached. The 24" x 24" flaps can be trimmed to fit nearly any vehicle. The four models below fit all vehicles, from full-size trucks to buses, motorhomes and trucks with dual tires.
4400 77-inch – fits full-size trucks
4400-73 73-inch – fits SUVs and midsize trucks
4400-69 69-inch – fits mini-pickups and small SUVs
4400-102 expandable from 91 inches to 102 inches for buses, motorhomes and trucks with dual tires
