Do you use your sliding window at the front of your camper?

One of the requirements for passengers in the camper while under way, was a pass thru to the vehicle. Both truck and camper required a slider for passenger s in the back.

I believe the common requirement for states that allow passengers to tide in the truck camper is two-way communication between the driver and the passengers. A pass-through could meet this requirement however a two way radio is the more common and effective solution.
