I went up on the roof up and took some measurements in preparation for installing the roof van. I’m planning on ordering the Maxxair Deluxe 5100K, I’ve heard good things about it seems that the only difference between that and the higher end Maxxiar fans is manual controls vs remote which is not something I would spend extra money on having.
Regarding the mechanical issues I had before (cylinder misfire) I went ahead and ordered the remaining 7 spark plugs, they should be arriving shortly and I’ll change them as a preventative measure that will hopefully fix any pending misfires.
