When we picked up our 2016 33BD we asked about getting the screens and were told that the furnace manufacturers had made significant changes to the exhaust ports and that none of the screens currently on the market will fit.
I have checked my local camping world twice since picking up our trailer and they are telling me the same thing. They have me on a call list and will let me know as soon as they get them in.
