[40's rock]

When I bought the rig, there was not passageway between the cab/sleeper and the RV box. I knew it would be one of the first projects...kids bopping back and forth during trips, utilizing the RV ac when stopped and just general access.

After searching for a prefab product...I decided to take it on from scratch.
Found the centerline of the rig, drilled a pilot hole thru to the RV box. Due to the bathroom position, the portal is set slightly offset to the passenger side.

Notice the phone on the wall and another on the dash, that was the previous communication system between cab and Lounge...state of the art for 1984...
