The gray water tank has been a pain in the butt since day one.  It doesn’t drain on the same side as black water. You need to run a hose to drain it if you are in a sensitive area. And there was the size, the venting, and the drain being about 6″ under the sliding door. I finally got tired of having to lay down in the dirt every time I connected a hose so I ran the drain out to the door. The problem with that (although I put up with it a couple of years) was you would end up with a hose right where the step needed to be.

So, I re-plumbed it and now the drain is in front of my rear tire. All the plumbing is hidden except for the drain end to which a hose attaches.

The underside of our Sprinter looks clean. Looking closer reveals some added components. (Click image for larger size.)

 

This is the drain for the black water tank which is inside the Sprinter. It is the only component you can see looking at the Sprinter from a normal view. All others are hidden.

 

 

The grey water goes into this tank has an 8 gallon capacity. If we are going for several days we carry a wheeled portable tank we can drain this into as it is a little small. We were limited by space so this is the only size that would fit.

 

 

Hidden away the hose for draining the black water tank. It is a little hard to get to but we don’t use it much and would rather it be hidden than easy to get to. The gray water tank can also drained with this hose but is normally drained with just a garden hose.

 

The propane tank has an 8 gallon capacity and runs the heater and stove. This should last quite a while and is much larger than we had previously.

 

 

Outside access is through this door. Also in this compartment is city water (used also to fill the water tank), shore power, cable TV (just in case we end up in a fancy place) and our extend-a-stay connection.

 

 

Here is the 4D-AGM battery and the fuel tank. Fuel capacity is 25 gallons.

The battery would have to be lowered with a hydraulic jack if we need access. It weighs 132 pounds and is 20.5″ x 8.13″ x 10″
