Well just from looking at my bed it looks as if the bed it twisted...I have pics but I don't think you can tell from the pics.

 

in the fourth one you can kinda see a little bit of a twist but nothing major.

 

Are their ways to fix that?

 

i have no clue.

 

looks to me like you have a case of ranger 'lean'. I think your leaf spring has sagged on the driver side..

 

Not to bad man its all good

 

I would look at the drivers side rear spring hanger to make sure its ok but your truck is new enough it shouldn't be rusted out. About half of the rangers I have removed the bed from had large washers as shims on the frame to level out the bed.

im sorry i dont know jack.... Spring hanger?

 

Just remember, your gas tank is right under there... so extra weight gives it a bit of a lean =)
