Got about the same price for a window from Winnebago. I was having some other work done by a mobile service and was pleased with what they did so I directed them on to several other projects. One of them being a large side window. I had already gotten about the same price point that you did from Winnebago. Mine is a Minnie Winnie. The mobile service took the window out, had the glass made, fitted and reinstalled for about $300. So far I'm pleased with all of their work. You might ask around at the RV Parks and see which mobile service they recommend. Good luck.
