Replacing a flat TRAILER window: is auto glass what I need?

Thanks, Steve! More great tips. I am narrowing down the options -- just spoke to a glass guy, who recommends laminated glass, not tempered. Tempered glass shatters when broken, like a car window. Laminate does not. He has to special-order tempered glass, cut to size by the supplier. Laminate can be cut in his shop.

Now to the big tasks -- removing the glass and then installing the new pane.
