I noticed when I was driving in the snow this year that my extended TB's running boards accumulated a fair bit of snow. Will mud flaps stop or cut this down and what are your opinions on mud flaps for the TB?

Yes... they virtually eliminate snow buildup on the running boards...
It makes for a nice buildup on the mudflap though!

Get the mud flaps. It will also help by keeping the rocks from flying up the lower parts of your TB reducing small rock chips.

I am buying them next week, well they will appear on the TB next week, I do not think my wife will notice...lol.. :evillol:

Got the moulded OEM mud flaps installed, they look great.
