The weight of the holding tank contents is not
calculated into the RV cargo carrying capacity
(this extra weight would reduce your available
cargo capacity). Traveling with full holding
tank(s) could possibly cause you to exceed
the individual tire ratings and/or the RV
GAWR or RV GVWR. Potential damage to
suspension components, such as springs,
tires and axles, could result. If your RV
holding tank(s) are located behind the axles,
the weight of the full tank(s) will reduce the
hitch weight. Trailer sway and other handling
difficulties can be the result of the hitch weight
being too light.
Dump the gray and black water holding tanks
before traveling to avoid carrying unnecessary
weight. If you are dry camping and cannot
immediately empty your holding tanks, reduce
your vehicle speed until you reach a dumping
station. When connected to the sewer drain
line at a campground, keep the “black tank
drain” valve closed until the holding tank is at
least ¾ full. This should provide sufficient
water to assist in complete draining of the
black water holding tank. Repeat as needed.
Before using the RV or after dumping the grey
and black water holding tanks, always add the
proper amount of deodorant to the black
water tank to prevent malodors and help
break down holding tank contents (unless
winterizing). Follow the deodorant bottle or
package instructions. Driving to a disposal
site will normally loosen any accumulated
waste debris or solids from the sides of the
holding tanks.
Never leave the black tank drain in the open
position continuously when connected to the
campground sewer system.

RAINS
There are labels on the exterior of the RV
indicating the location of the grey tank drain
and black tank drain (also called dump
valves). Always drain the black water holding
tank first so the following grey tank waste
water can help rinse any solids or debris from
the dump outlet and sewer hose.
Fig. 7.8 Black & Grey tank dump valves
1. To make drainage easier, level the RV.
2. Remove the sewer hose housing dust
cap, and attach the sewer hose (customer
supplied).
3. Place the end of the sewer hose into the
approved dump station.
4. Open the black tank dump valve (close
the dump valve when the black water
holding tank is emptied).
5. Open the grey tank dump valve (close the
dump valve when the grey holding tank is
emptied).
6. Remove, clean and store the sewer hose.
7. Close the sewer hose housing dust cap.
Do not add automotive antifreeze or
caustic chemicals such as laundry
detergents into the holding tanks. Although
these products may have a deodorizing
effect, they may damage the plastic and
rubber parts of the plumbing system or the
components.
Never travel with full black or grey water
holding tanks. This not only wastes your
fuel but depending on the location of the
tank(s), it can affect your tow vehicle
handling characteristics.
