Here's my flaps, they are made by air hawk

 

For pulling boats and trailers, nothing protects like the DuraFlap. Your choice of width and length; and I did not have to drill holes in the metal of my truck.
Look at the coverage in the rear fender wells. I do not need any liner.
Splash guards just do not give any protection.

 

here are some pics of the no drill weathertech

 

The last 2 posts show the difference well of the coverage you get with the full size mud flaps and the contoured splash guard.
It just depends on the protection you want, the warranty you want and the look you want.

 

They do a great job at keeping the mud off of my boards.

 

Id go with the homemade set here. I'd modify them though. I'd want them to come off easily. Perhaps square stock to slide over receiver held in place with the same pin used for your ball. I'd still add some weathertech for everyday use.

 

Lol I don't need Em or will never get Em probably even when I go 12 wides. If I ever get a camper like I plan on doing I might look into Em but my pic was just for reference for people on here

 

Why are there no naked lady laying back or yosemite sam back off mud flaps?

 

Duraflap offers some of those weights too:
