So proactively im planning on replacing the Studor vents.<br/>2001 3610 coach<br/>How many vents and locations? 4? Shower would be 5?<br/>I think there may be one in the bathroom closet for the cloth washer hook up. We have no plans to ever have a washer, can this one be plugged or should it still be replaced?<br/>Is there a particular brand that will provide good service life?<br/>I thought...
