Joy,
  I saw that you mentioned window screens.  This is not in regards to the sides but for the front windows that may be easier.
  I met an older gentleman in Milwaukee that:
  Opened his front door.
  Took black nylon screen material and draped it over the front window frames.
  Cut out a general shape of the window but a bit larger.
  Sewed it on 2 sides--excluding the bottom.
  Added some cheap flexible magnets to the bottom edge.

  He now just opens his door, covers the window frame with the screen pockets and his windows are screened. If he gets cold at night, he winds up his window.
  Super cheap and EASY to stow.

  Not sure why I  haven't done it myself yet!!

  Incidentally; I just removed my plastic side window screens (broke one tab off--rats.) and used Krazy glue to mend the broken frame. Then used same glue to reattach the loose screen--used plastic barber's hair clips to hold the screen down while drying.
  For the back, got a rear air-lock extender for the back hatch--to open it sightly with the screen in place yet still keep it locked. You can buy one from Eurocampser.com($12) or make one. For the skylight, finally I broke down and bought a reproduction screen with blind.
  I realize your resources for fabricating may be limited where you are now. Just wanted to pass on the info.

  Good luck

  Does anyone know where to get screens for the sliding windows? The plastic
frames of both of my screens are broken and they won't stay in the windows.
Last night for the first time I stayed in a place with monster mosquitoes,
and it would have been nice if the screens had worked better.

Or if anyone has a pair to sell, I may be interested.

I've got an '89 - I don't know if they differ from year to year.
