Ekro -- I have a 2015 Vegas 24.1 and the same microwave/convection oven by HighPointe. It was standard equipment on my RV.
Check yours closely to be sure. You may already have a microwave/convection oven. There should have been an operating instructions leaflet in the canvas Thor bag that has all the literature provided by the factory.
By the way -- my dealer replaced my microwave/convection oven while we were still under warranty because the cooling fan quit working. They called HighPointe and HighPointe sent them a new microwave/convection oven. Took 3 days for the new oven to come in and the dealer took about 30 minutes to remove the old and install the new.
