Best solutions for vent fans

We are getting closer to purchasing our first RV. Follow the link below for the floor plan layout to get the layout of the bathroom area configuration.

Nexus RV Phantom 28P floor plan

We plan on adding two vent fans on the ceiling, MaxxAire Deluxe. One in the rear bedroom area and the other in the living area up front. This is where the standard fan in the commode area comes into question. If one were to leave the bathroom door partially open while not in use, is there a need for a vent fan in the commode area at all? I have not discussed the possibility of deleting the bathroom vent fan with Nexus RV, but it seems to be an easy change to accommodate at the time of construction. I have read on this forum that one does not want the vent fan in the commode area to be running while flushing the toilet. This would make sense since the airflow would tend to pull odor from the black tank. I would think the additional vent fan in the bedroom area would take care of moisture concerns from the shower area.

I do not know if there is a concern of the original vent closure on top of the RV to crack or leak over a period of time, but if it is not there at all, no worries at all. Am I over thinking this or should I just add the two new vent fans and leave the original as is?

Thanks in advance for your advice.

  • I'd leave the little whir and buzz in the bathroom and put the second maxxaire in the living area. and no you don't want a maxxaire (good) fan running in the bath room when you flush the toilet as the black tank will vent thru the bathroom. do it once and you'll never forget to not do it the next time.

  • IMO, the bathroom is the primary location for a good vent fan. Not just for bathroom odors but also to vent shower moisture.
    Bringing the odors and moisture out into your living area is not a good idea.
    I understand the fan drawing odors from the black tank when you flush, but flushing is fast - the valve is only open for a couple seconds. I get in the habit of turning the fan off when I flush.

    But when I shower I like to have the fan on to get rid of the moisture as quickly as possible. It is already hard enough to keep the humidity down in an RV.

    I would put the good fan in the bathroom first and if you want a second, put it at the opposite end or in the living area.
