It's academic, because there is not going to be a one-piece windshield that fits into that existing frame. Nor can you just remove the center strut without affecting the structure of the front cap, of which it is an integral part.
Windshields are not a one size fits all - the opening is designed to have a certain piece of glass mated to it. The RV maker chooses an existing windshield from some other vehicle (it's far to expensive to have a unique one molded for each RV) and designs the front cap to match it. Hopefully he does this well, so that it doesn't flex and pop out or crack. So, What you see is what you get.
