Minivans aren’t often considered to be noisy places, but if you own a 1976 VW Microbus Camper, that’s certainly not the case. When driving at high speeds, the Microbus Camper vibrates and rattles, the wind noise comes rushing into the vehicle, and this makes for an overall very noisy environment. So to fix this, Caleb here is installing a rotary phone intercom system into his van so his backseat passengers can hear the drivers and vice versa. Does it work? Yes, it does.
