Actually that is an excellent question I mean that part of the room can get COLD or HOT depending on time of year. not comfortable at all. But I will attempt and answer and give a suggestion or two.
THe window is not just a window. It's an ESCAPE window.. And heaven forbid there is a fire in the RV.. ANYWHERE other than the bed (If it is the bed you are already in tribble) YOu open the window and basically dive or sommersault out.. Do not delay. Do not reach for trousers.. Just get outta there before the toxic smoke drops you like a rock.
What I DID
I have a hand woven wool blanket that is basically useless. Save as a wall hanging. The wall I hung it on.. Said window (Between Window and shade)
Reflectx is the other suggestion .
