I'm with you guys about door windows but if given a preference mine would have the glass only in the side cargo doors. I have a partition curtain that can be easily pulled aside when approaching those blind intersections with stop or yield signs only.

Security wise a visible armed alarm warning light and keeping stuff out of sight is probably the best first line of defense. After all if they really want inside there's not a lot we can do that will really keep them out.

I've been hit twice in my own drive way but its because my high-value tools were on full display.

 

On a 2008 E250cargo with door windowsand new gaskets is a vacuum cleaner driving thru an agricultural area sucking in poison sprays. Gasketing the doors with Wal painter tarps at $1+ stops that....masking tape n hang close the door.

The body/frame flexes door [position so even with new gaskets...

Bought a squirrel cage fan....
