Full mud flap

We actually saw folks removing them on our Alaska trip and we saw a layer of large rock laying at the base of their towed's windshield. We just had the stiff flaps behind the tires and didn't receive any damage.

Later on while driving through Salt Lake City in a heavy downpour, I, the passenger at the time, took note of motorhomes going in the opposite direction. Those with the long stiff flap had a high arc of water spraying the toad's hood. Those without the flap had the water aiming at the tire area of the toad.

I agree with Dutch...they kick up more and larger detritus then not having one at all. Even traveling to Alaska. But chains seems to be the most popular way to hang them from all that I've seen.

If it does not have an angle iron at the top it needs to be bolted to angle iron the entire width and then hung to coach frame allowing about 4 inches of clearance from payment so as not to kick up debris.

Short chain with one of the threaded links to attach. If the height is properly set, there won't be an issue with road debris.

Make sure that you mount the chain at an angle. If attached to a 36" wide frame, you want the chain attached to the flap at about 40" apart. If you attach to the frame and flap at the same width, the mud flap will rock from side to side.

Short chains is the most common way, but if you're towing a toad, I don't recommend installing one. They tend to kick up road debris, gravel, etc, into the front of the toad.
