My dealer asked me this regarding sliding front window...
You going to camp in Grizz country? I replied of course, someday I'm heading up to the NWT and into Alaska.
Well consider this...
If you wake up to the sounds of Grizz outside your camper, are you going to wait for him to leave?
Or send the wife out the the camper door first, running in one direction to distract Grizz while you jump out of the camper and hightail it for the dirver's door? Start truck up and rescue wife from Grizz?
Or just shimy throught front window into truck and drive away to a safe distance?
I didn't even need to ask wife which option to choose, sort of figured it out on my own. But the ventalation the window affords is very nice as well. Worth the coin IMO.
