Andy,
I think that the heat tape on your '95 is configured like the heat tape on my first Beaver, a '93 Patriot on a Spartan chassis. If so, the fresh water tank is mounted in front of the front axle, and the heat tape is r
run in a zig zag pattern across the bottom of the tank between the tank and the insulation to prevent freezing in very cold weather.
The front end of the floor ducts for the hearing system terminated in the water tank housing, so if the heating system is running the heat tape is not needed, unless the weather is extremely cold.
