I am in the process of installing a "Visa 319 MSD" in our 1987 Catalina 22 New Design.
This 18 litre (4.75 us gallon) portapottie MSD is from a Canadian company
It's a newish product from what i can tell.
Price was good. (Cost me the equivalent of $140 USD from my local brick and mortar marine dealer)
Seems well made. (Time will tell)
Has a dual action pump instead of a bellows. (Instructions say it needs to be lubricated occasionally)
Parts are available from my local marine supply store.
it comes configured for MSD use so you can hook it up to a pumpout and vent, but the a normal cap and spout are included if you ever need to dump in the old fashioned yucky way. The spout is stored in the bottom of the waste tank.
The pottie is too tall to have the v berth insert in place. Opening the lid makes little difference because of how the top section is made. This doesn't matter to us, because we took the v berth cushions out and use it simply as storage. YMMV.
The height is perfect for sitting on it, unlike our old 2 gallon dometic.
Hold downs attach front an back. They lock onto little ribs on the waste tank.
Time will tell how well they work. (@Gene Neill has posted complaints about how his Thetford hold downs work. Our old Sanipotty was ok, but the clamps were a bit loose due to age)
The waste tank outlets are configured differently that the Dometic units, but I don't think that will be an issue.
I will be running the vent and pumpout hoses to the same location as @AaronD did for his install.
That way i can use some left over plywood i have from my galley modification and create a nice removable cover for the hoses against the port bulkhead.
Stay tuned. Time to get out the hole saw.
