This is whatwe have done. We actually took out the frosted glass and replaced it with the same size (tempered) clearglass. We wanted more light at that end of our Zinger.
I installed vinyl mini blinds - bought at home depot. There was actually justenough room between the screen doorand door for this. I drilled through the mini blind bracket andused the existing door window mounting screws to mount it. I used double sided tape to mount two slats to cover the mini blind bracket - there was lots of slats left over after shortening the blind.
This is the second trailer in whichwe have done this mod. The door mini blind pretty much matches the factory mini blind covering the kitchen window.
