Roadtrek Zion dual dumping system

I installed it on the large black tank, and it had a quick disconnect. I had to crouch down to connect the water hose. On the 190 P you still have to hose out the smaller tank once in a while.

The piece of clear hose stays connected to the Tornado, and you mount the other end in a convenient location. Mine didn't have the vac breaker.
Of course you have to get under the van for the install.

Did you have this installed into your black tank - and how did you make the connection accessible without crawling under the van?

After checking it out, this arrangement appears to be less complex than Roadtreks previous masceator setups and offers the advantage of a dual dumping system. Moving the black tank gate value to the side of the Zion has eliminated the long control rod for the black dump value which broke on my setup. I could find nothing about a gray tank gate value - where is it?

In the short video about the dual dump system, just off to the left there is a quick glimpse of the grey and black tank gate handles. The video never shows these being pulled and only shows opening a gate for the gravity dump which seems to be done in addition to pulling the usual handles.

You can just hold up the slinky and put the water right into it to fill the tanks. The water running backwards often will get more stuff broken loose or debris dislodged if it is stuck.

Plus, no hose or buckets to drag into the van.

Absolutely! I have to do it now with a hose that comes through the van to the toilet. The last trip of the past season when we had to do this it was pouring and it never got done. And it never really works very well anyway. It would have been so much easier to have the ability to connect a hose to a slinky outside and just turn on the water.

The dual system sounds great to me. I have the standard Roadtrek macerator and it has been fine but there is no way to back flush the black tank through the hose and I would like to have that ability. A gravity system can always have a portable macerator added.

I would like to have this new system retro-fitted to my 11C190P but it sounds like Roadtrek is not going to make that available.

I got very interested in the Zion until I learned there is no outside storage compartment - no place for a wet/muddy hose, power cord, etc. other than inside.

Robert-i'm going to fit a plastic box in the gap between driver side couch and back door on the zion-i think it will hold some stuff. other than that i guess it's a plastic box inside a drawer-what can i say-i love the zion-lol- most of the sprinter models are like that if e-trek package
