Hey Fellow Towers,
If your interested in Custom Reflective mud flaps for your trucks try USA Flaps.com I order a pair for our new truck and they did an outstnading job of matching our logo and they even are reflective. And you can order 1-pair (alot cheaper than they use to be for a single pair, i.e. 1-pr 36x24 with logo-reflective in rubber were about $88 with s&h, I paid back in the 80's over $100 for a custom pair and they didn't do exactly what I wanted.
These really look good with the chrome or stainless mud flap weights and flash those guys behind you with their HIGH Beams on pretty good, usual turn em off after a few flicks of the mud flap weights flashing them.
As Martha would say, "This is a good thing", I love them.

And yes, I am still smilin big, really happy with the Sterling (last months MPG average was 10.6mpg and ain't even broke in yet only 6000 miles.)
Cool! Always wondered where people had those made. 
I was thinking about custom flaps and pulled up this old thread.
