To install a Fantastic fan in a 2003 Airstream Bambi you will need to steal/borrow power from a near by light. The power to the lights is a switched power so in order for the fan to function you will have to have the light switch on, but if light is not needed you can turn the switch off on the fixture itself.
The fantastic fan has a 3 amp fuse built in and the wiring in the trailer can handle the additional load.
There will be no need to conceal the wires, because they will run from the light fixture to the fan between the interior and exterior aluminum sheeting. To access this you will need to first remove the inner flange for the manual vent. Be sure to set aside a full day for the two fans, the most labor intensive part of installing the fans always seems to be, the removing of the old manual vent cover exterior housing.
On a fully charged Group 24 series dual battery system, running a single fan on low setting, and thermostat set on a comfortable temperature, you should be able to run at least 8 hours.
For Peace of mind, An Airstream service facility can install and provide the 6000 series Fantastic fan for around $400.00
