2021 Seneca 37k heat

The vent in the small bathroom puts out a ton of air and heat. Not really that much needed in there. Anybody find a easy way to reduce it?

The rear bathroom heater vent under the shower seems to have no air volume.

We have the 2022 37K and the rear bath vent is really a poorly designed 2" vent cobbled together with several others and not a heating duct at all.

Same issue with high volume of air in front bath on our 37K. I haven't fixed it yet and think it will take trying to make a gate at the main box. I found that the problem with the rear bath is that if you open up under your bed you will probably find an unhooked duct or a crushed duct. Mine was kind of both half unhooked and crushed.

I made a post about the same problem with our RB 1/2 bath. In my post about it, another member made a post of a similar mod he did to his K…..here is the thread.

There is also pics of what I found under our bed of the heater ducts feeding the rear bathroom vent in the link above. There was a crushed red and an excess of ductwork and once straightened out by removing excess and replacing the tee, the rear vent has great airflow.

I took a couple of pics from under our bed. As you can see there are a couple of spots where there are 2" tees that go into the underside storage bays before heading off to the shower duct.

From a previous post, I have rerouted and cleaned up about half of this wiring mess.

I was having the same problem with our bathroom vent(2018 FS). Solved it two ways…
1. Order and replace bath vent cover with one that can be open and closed.(Amazon)
2. Opened up the vent on the dinette side, opposite wall, and removed about 3’ of excess duct work.
Works as it should now

Since I saw Brian's pic from inder the sink, I decided to open up mine. Why would you screw part of the floor and then staple glue the other part? Either you want it to open or not.
Anyway my "heating ducts go under to the propane tank and one other bay, neither makes any sense .

Here's a pic of the heating duct.

So, it took a little while, really about ten seconds to decide to delete the under storage ducts and just heat the bedroom and rear bathroom. Two of the under vents went to the propane storage which is open to the world. Three under ducts and the rear bathroom vent all on one two inch line is silly.

This is a 37K.

on my 2021 37k the 1/2 bath was way to hot, cut out some twisted ducts, unhooked the duct that went to 1/2 bath cut a hole and installed a vent on the lower right side below the fridge now the heat blows into the living room, works great

I switched the bedroom and bathroom vent covers, so I could just close the bathroom vent.

Got a round electrical box cover with 1" knock out. $ 2.49 Placed in duct work under fridge. Works great. Get heat under shower in rear bath and still warm in half bath. Now to get vinyl flooring in half bath back in place after excessive expansion from the heat.
