I see you talked about a running board change.
Did the new ones stick out farther than the stock ones?
Did you do the 07 Escalade mod?
2004 Yukon is difficult for my wife to use the stock boards. They don't stick out far enough.
Also 17" tires don't help. She is the primary driver.
I will plow snow with this vehicle but with my extra set of 16" tires more aggressive thread pattern.
Thanks for your answer.
