2010 and 2011 + newer bed dimensions for cap
 

I am thinking about buying a new SD, but I have a nice Raider Nomad cap on my 2010 that I would like to use. Are the bed dimensions the same?
If I get a truck without the tail gate step, is the tail gate the same?

The beds are the same dimensions. All beds from 99 to current are the same dimensions, with the only difference being the tailgate top shape. I'm not sure if the gate step changes anything or not though.

Thanks for the info.
I am going to contact my Raider dealer and see if the plastic piece on the glass window can be ordered. If it can that would be great.
