You could do it cheaper by just getting the plastic wrap from Lowe's that you put on the inside and shrink tight with a blow dryer. It's meant to keep out drafts. That might help. I bet the windows are really expensive. Anything RV is outrageously expensive.
I agree that is probably the best route to take and if you don't need to actually see outside the window even the thicker "Bubble wrap" tapped or wedged in the window frame should provide almost the same insulation value as the much more expensive double pane replacement route.
I'm going to try some of the bubble wrap in some of my windows and ceiling vents during our upcoming Dec to Feb roadtrip this year. We're only going to Fl so this will be a "TEST LIGHT" experiment:p
