Bed Shakes
I know that there is probably a lot of posts on this issue but search can't find anything relevant to me. So I am going to post a new one. 

I have a 08 Supercab XLT 4x4 with 6.5' bed. And I notice that when I go over bumps my bed wiggle/shakes. Sometimes I can even see it wiggle when just driving. Is this normal. My Mechanic has said its normal but I don't know if i buy it....so any of you have any solve for this? I know awhile back someone said to put in a tool box and load it with tools but is there anyway to fix it and keep my bed empty? Thanks guys!
