TRANSPORTING YOUR QTAC
Gross Vehicle Weight Rating
•Ensure that the gross vehicle weight rating (GVWR) of the QTAC carrying vehicle
is sufficient to support your QTAC unit and a full tank of water, plus any
equipment, fluids and personnel that you may wish to carry. Alternatively, you
can reduce the volume of water in your QTAC to maintain a GVWR under the
limit of your vehicle.
General QTAC Mounting and Fastening
•Ensure that your QTAC unit is secured to the carrying vehicle. Two main
mounting approaches are available for your QTAC unit:
oStrapping the QTAC down just inboard of the grab rails located at the top
of the water tank (see Figure 5).
oMounting the QTAC at the flanges (see Figure 1and Figure 5), located at
the bottom of the water tank (the flanges have been machined to accept a
variety of mounting hardware options).
For both mounting approaches, ensure that the bottom of the QTAC (including
the mounting flanges) abuts a firm, flat surface or rack. Avoid significant
leveraging of the mounting flanges. See Figure 5for examples of proper and
improper mounting surfaces.

Special Precautions For Carrying a QTAC On Ride-On ATVs Or Side-By-
Side UTVs
•Ensure that the area to which you are securing your QTAC is an approved
loading area for your ATV or UTV.
•Ensure that the weight of your QTAC does not exceed the maximum
recommended weight of the ATV or UTV loading area to which you are securing
your QTAC.
