My truck is no pavement princess. I'm actually pretty hard on my trucks living in sportsman paradise. I took the truck down a bumpy flooded road and after I got out I noticed a rattle under the driver floor board when I hit little bumps in the road.. I can heard it and fell it under my feet... I have bumped on and shook on everything under the truck and I can not for the life of me figure out what it is... Yall have any thoughts??
