I'm adding AC to my 13' scamp
. Roof mounted was my first choice (expensive, but didn't want to lose storage), but it doesn't sound like my 2009 Scamp
was designed to support it. I intend to vent it out the floor. Hot air wants to rise, so forcing it out the floor is going to take a fan.
My question is how many CFM do I need. I know there are a lot of variables that largely depend on how much hot air I need to remove and how much "air resistance" I have due to not having perfectly open flow. I am debating a ~100+ CFM vs. a 200+ CFM fan. I am leaning the 200+ CVM fan just to be safe. Anyone have any real world experience to guide my choice?
Also, I hear of numerous people using the 3-5" muffin fans. Does anyone have experience with the blower fans favored by the marine industry and reasons why to choose one over the other? (example blower link
Thanks for the help (as always)!
