----a little light or something on the dash to remind me that the damn rear slider window is open.
With the cab so large as mine and the slider so far back, its easy to forget its open.
Need some sort of indicator showing that it is open.....like how the dash makes a noise when the key is left in the ignition or the lights are on.
I have left the darn thing open a few times now overnight, and found damp back seats due to rain.
Wouldnt mind a defroster on the rear window too....but maybe they have those and mine just doesnt?
