Can't see who's knockin' at the door !

[RnR]

Proud owner of the 3295RK (2002). Bought this unit just over a year ago and have not had to take it back for any fixes, adjustments, repairs, or warranty work. Completely satisfied with quality, workmanship, installed accessories, great dealer, everything a buyer prays for when purchasing a big ticket item ! Absolutly love everything about this trailer. Glad my wife and I took the time to go through 25-30 trailers before we walked into the Montana. We both looked at each other and said this will be the one ! So far I've found only one small possible flaw in the design of this model and perhaps someone on this forum has come up with a solution.
While inside this trailer, if someone comes knocking on your door at midnight, or any other time for that matter, you can't look out any window of the trailer to see who is knocking. Impossible to see the right side of trailer at anytime. So far the only solution I can come up with is possibly install a rear view mirror up by the bedroom window but refuse to drill any holes or use glue. One other solution would be to change the frosted glass window in the door but I don't want to turn this into an expensive project, for something that has not been a problem yet.
Anyone have any suggestions ?
Thanks,

Garry
