380FL-R Sewage Tanks?

[jorozier9]

New GD owner and new to RVing (less than a week)

I was under the impression that the 380FL had two gray and two black tanks. This was only reinforced by the RV dealer at sale, by the control panel which is marked for two each and of course by the four drain handles in the rear compartment marked Gray 1 and 2 Black 1 and 2.

However setting up the first time I immediately see I have only a single sewer drain, not two. Reading the boards and googling I'm hearing that (a) the control panels are generic and not model specific; same for the drain handles in the bay; and that the more common configuration for a solitude is two grays and one black. I drain everything and test by pouring water down each drain to see which tank is feed by which drain but if someone could confirm/answer for me:

How many sewage tanks does the 380FL have and what types are they (gray, black)?

If I only have three tanks, why four handles?

Do I only have the single sewer drain on the side? I was expecting two drains and the need to connect two sewage hoses with a "Y" again supporting front and back pairs of gray and black tanks.

Thanks in advance. This board has been tremendously helpful in getting my wife and I up to speed quickly.

With a capacity of 106 gallons for gray and 106 for black, I would say you have two of each. Our 303 has 2 gray water and one black water but all three tanks feed a single drain line from the rv. I unless you have another drain for a rear tank at the rear I would imagine all four tanks are plumbed to a single gray/black water sewer outlet.

Perhaps other 380 owners will chime in.

You have 2 of each.

You don't need two discharge pipes since the bathrooms are relatively close to each other.

If the half bath were at the front of the trailer, then you would need another discharge pipe as the run would be too long to get a good dump angle.
