Mirror Suggestions for Running Doorless

I am taking my doors off for a long weekend trip and am looking for suggestions for temporary side mirrors.

 

Bicycle mirror keeps the cops off your tail. Are you gonna be running tube doors? Doors are actually required around here.

 

The way I read the AZ laws-If you can see out the back window ( no cargo or trailer issues) then you don't need them.

The overall door question is a good one tho. Might be worth a call to the po-pos to get their take on it...

 

As I understand it there is no law requiring doors but the law does require side mirrors on all post 1967 vehicles.

I have heard this rear view mirror only thing from a couple Jeepers that run no side mirrors and whether or not that is legal, I'd like to run mirror so I can keep track of people behind me on the trail and I like to angle them in a little so I peak at my rear tire placement.
