"caburke2"......How far back you want to hang it depends on what is there to bolt it to and what looks good to you. The father back that you install it, the more it's going to move up and down (long rear end pivoting up and down).

A simple installation is an "eye" bolt mounted to the frame and a similar "eye" bolt mounted to the flap, or a bolt though the flap with a link of chain bolted to it. A "quick link" mentioned above, is a good way to then connect the two together.

Now here is an important factor when mounting the flap. If you place the "eye" bolts or mounting brackets 36" apart on the frame and 36" apart on the mud flap, the mud flap is going to swing left to right ( driver's side to passenger side) as you go down the road. The mounts on the flap need to be spread a few inches farther apart than the mounts on the frame. This will keep the flap centered when going down the road.


This photo will give you a good idea of how to mount the flap. This is mine, I later shortened the connections to lift it higher.

The minimum distance is 4", sitting on level pavement. Any lower kicks up rocks and debris from the road.
I have a DP, the mud flap touches the pavement when air bags are deflated, 4" clearance when inflated.

Same here, plus I use as Protect-A-Tow mesh shield between the MH and toad for complete protection!

Crasher.
Was the full width mudflap dragging the ground and kicking up rocks? I'll be pulling an enclosed trailer come spring and just curious why you had so much trouble with yours.

However have you noticed that most "fly up" at highway speeds... (providing little protection)?

That's what mine does. When the sun is right I can see the shadow of it flying in the wind in my rear camera.

Mud flaps that sail are usually built from thin rubber or plastic and the metal supports aren't heavy enough. My Newmar used plastic and it always looked like bad, the plastic was greying. I replaced the plastic with rubber from DuraFlap, a sponsor on IRV2. Mine is very heavy and doesn't sail. It also looks better now that it's made form rubber.

The UltraGuard flap is heavy and when attached to the angle iron support it is heavier. Mine are attached by two eye bolts on the chassis with a "Curt Quick Link" and two more eye bolts on the angle iron. No chain or other dangling mess. The UltraGuard can be cut to have the ground clearance. I have a straight back rail on the MH. Others I have seen have an up-sweep rail and maybe a chain or extension is needed in those instances.

I towed with just the UltraGard when I had the '07 Saturn, and now with the '13 MKX I also have the KarGard II from Blue Ox. Both work very well.

Mine is the heavy rubber Ultra Guard full length stone guard. It doesn't sail high, I can see it moving in the camera.

Here is how mine is mounted......I also had a custom thicker stainless steel anti sail plate made to be sure it stayed down. There is not one ounce of movement back there and my trailer stays ding free.
I also bought stainless steel anti sail plates for the mudflaps directly behind the tires front and back from a custom trucking website and I think that helps as well and they look awesome!!
Just in case you guys (Sims) are wondering......My friend Ryan made me my custom anti-sail plate for my full rock guard.....it is sweet and was half of what the online companies want to make a custom plate.
Hey Sims......notice my rear camera placement in the picture? lol

I second this motion. No more flap, no more rock chips.

How do you figure a flap causes rock chips?

The only reason a rock flap ever causes chips is because guys run them too low. If you run them low they actually will kick up rocks and debris on the highway. You really should run about 4" off the pavement to prevent this from happening.
