Steve, I don't plan on using mine either being I have a AMNPS too. Todd and I were just interested in the engineering differences. We're curious folks.
Todd, No holes in the end of housing on either one. Maybe the 2011 model had them. I think I found the major change. Look at the pics of the tray rail below. New one now has a little "lip" to keep the tray in the housing instead of just being able to slide straight out.

dward,Hmmmm...... Wait a minute...
Seems like there was another thread on this a week or two back and the clerk at Bass Pro told the poster that the company (MES?) had sent someone out and "fixed" all the units (which if you query the model number at the MES website, are drop shipped from China and not directly from MES in USA.
Yep, I thought that tale was BS when I read it then too.....
