We are building out a 7x12 7’ high v nose, we know we want roughly 3 windows, and I know how to install traditional house windows, and RV windows, my question is, we have added some traditional 2x4 framing on the inside of our trailer to accommodate some extra insulation (wife is very concerned she won’t be warm enough in the cooler months with a mini split so we compromised and are adding some extra insulation between the skin of the trailer and interior wall using the space in the 2x4 framing) would you still use traditional rv windows and just have a 4” deep window sill? Or do something else?
