A lot of people think that most parts are common and will fit any kind of RV. The truth is, there are very few things in the world of RV parts that have a “standard” fit. For example, a lot of people come in needing vent lids as theirs have been damaged by wind or hail. Vent lids do not have a standard fit or style. Many people are surprised to learn that there are many different styles of hinges that are used. Just as we explained in the last question, there is no way for us to check a database and determine which vent lid your RV has. We are going to need the broken piece or a photo of the vent lid to confirm!
