Hi, traveling on vacation on 07/02/13 at 8:45am on i82 west in Yakima, Washington and came up behind a truck that had your logo on the side of the door. This truck was hauling dirt and rocks without being covered. Rocks were flying out of the back end onto the freeway. I am so glad my wind shield was not cracked by these uncovered rocks. Would really appreciate you covering your trucks. Thank you for taking the time to read this. Marti petersen at 408-416-7358.
