GRAY WATER HOLDING TANK
No special preparation is required. However, placing a small quantity of chemicals into
this tank, such as baking soda or a Thetford chemical, will reduce odors from food
particles in the system.
WARNING: We recommend that you DO NOT travel with waste in your
holding tanks. Full holding tanks are not calculated into the cargo carrying
capacity of the unit and the extra weight will greatly diminish the cargo
weight available to you, possibly causing you to exceed the gross vehicle
weight rating of the unit. This can damage suspension components, such as
springs, tires and axles. If your model has the holding tanks located behind the
axles, the weight of a full tank will reduce the hitch weight. Sway and other
handling difficulties can be the result of the hitch weight being too light. If you
are dry camping and cannot immediately empty the tanks, use caution when
towing and maintain lower speeds for better control of the trailer until you
reach a dumping station.
DRAINING THE TANKS
On the outside of the trailer are labels (Fig. 4-19 & 4-20) that indicate the location of the
gray and black holding tank drain. A typical set up of the tank drain and termination
valves is indicated in Fig. 4-21. Look for the labels to locate the drain and follow the
instructions below to empty the tanks.

When hooking up to the sewer drain line in a campground, keep the termination valve on
the waste tank CLOSED until tank is at least 3/4 full. This will provide sufficient water
to assist in complete draining of tank. At this time, open the termination valve to empty
the tank (see directions for draining below) and close the valve when the tank is empty.
Repeat this process as needed, but NEVER leave the termination valve open when
hooked up to the park’s sewer system.
