1. PACKING THE CAMPER TRAILER
WEIGHTS & LOADS
Before packing your vehicle and trailer, it is important to know and
understand the following terms and load limitations imposed upon
your TOW-VEHICLE by the vehicle manufacturer.
1. GROSS VEHICLE MASS (GVM): The maximum allowable weight of
the vehicle when it is fully loaded. (This includes everything : the
driver, passengers, accessories fitted to the vehicle such as roof
racks and bull-bars, luggage, fuel, weight on the tow-ball etc.)
2. GROSS COMBINATION MASS (GCM): The maximum allowable
COMBINED weight of the loaded tow-vehicle AND the loaded
trailer.
3. TOWING CAPACITY: The maximum weight of a fully loaded trailer
that the tow-vehicle can legally tow. NOTE: If the tow-bar fitted to
the vehicle is a factory-fitted or dealer fitted item, it will inevitably
match this rating. If however the tow-bar is a non-genuine after-
market fitment, it would be prudent to check the plaque fitted to
the tow-bar to verify what the Towing Capacity of the tow-bar in
this case actually is.
4. TOW BALL MASS (TBM): The maximum downward weight that
can be applied to the tow ball (or equivalent). NOTE: It is also
important to verify that the TBM rating of the towbar can
comfortably accommodate a ball weight of at least 12% of the
trailer’s ATM.
Similarly, know and understand the following terms and load
limitations imposed upon the TRAILER by the trailer manufacturer (i.e.
in this case Cub Campers):
5. TARE MASS: The weight of a trailer as it is generally delivered (i.e.
with no water or gas in their respective tanks.)
6. ATM (AGGREGATE TRAILER MASS): The maximum permissible
weight of a free-standing, fully loaded trailer (i.e. unhitched).
