Is the vent on the outside a standard size vent that you can buy from Lowes? Does the vent touch the molding on the outside that runs down the side of RV? We bought a louvered vent from lowes and drilled a hole from inside the closet where it said to "drill here" and when we try to attach the vent on the outside it touches the molding. We would have to turn the vent slightly at an angle to make it work. I'm wondering if the vent that comes from Splendide is slightly smaller than the standard one from lowes.
