Hey, well, i have an SLT, i belive, without the foobard mud flap design. I'm not sure weather to go with the rubber floppy ones, or the molded ones... I think the rubber ones may hold up better in cold weather (i'm in Alberta, Canada). Just wondering if i could get some feedback on this...

 

The flat rubber ones are nice and big, and actually keep most of the crud from getting tossed into the truck. I looked at the molded ones and they were pretty small.

 

I have the molded ones they seem to keep the sides relatively clean, huge difference from none to them. We don't have tar and oil on the truck anymore.
