My Starcraft did not have a fan in the kitchen vent. The bathroom did. Neither had a cover.
Decided I absolutely needed a good fan in the kitchen. Pulling down the lower cover of the existing vent reveal DC wiring run past the vent. I'm not 100% what these lines feed, but taped into one anyway. Installed a Turbo/Max - what a great unit! 1.4 amps at low speed (~500 CFM) and 4 amps on high and move OMG air!
At the kitchen is in the back and bedroom in the front, with the fan blowing out this should work well. We can open the bedroom windows and run the fan on low at night - keeping us nice a cool. I'm seriously thinking about the Maxx window vents to give the air a way in when it is raining.
Mandatory MOD IMHO....
