Tip of the Month, March 2015: Are you overloaded?
No one would overload their vehicle like this, right?
Well before you answer that question, let’s examine what you need to know about loading your RV or Mobile Clinic and how overloading can affect your SAFE operation.
GVWR (Gross Vehicle Weight Rating) is the MAXIMUM permissible weight of your vehicle, FULLY LOADED and includes liquids, passengers and cargo. (GVWR=NCC) Important because you are unsafe operating near or above this weight.
GCWR (Gross Combination Weight Rating) is the MAXIMUM allowable combined weight of the motorhome and the attached tow vehicle. Important because exceeding this weight places stress on the vehicle’s engine, cooling system and transmission, that exceeds the designed and engineered limits. GCWR assumes the towed vehicle has its own braking system.
GAWR (Gross Axle Weight Rating) is the MAXIMUM permissible weight each axle assembly is designed to carry, as measured at the tires (including tires, wheels, springs and axle). The GAWR assumes that the load is equal on each side of the vehicle. Important because you want your vehicle to be weight-balanced.
UVW (Unloaded/Unladen Vehicle Weight) is the weight of the RV AS BUILT at the factory with full fuel, engine oil and coolant, but otherwise empty. (GVWR=UVW+NCC). Important because this number is needed to calculate what you may safely store aboard the vehicle.
NCC (Net Carrying Capacity)is ALL YOUR STUFF; including all occupants, food, tools, LP gas, fresh water, personal belonging, after-factory installed accessories and the tongue weight of any towed vehicle. Weight Distribution also plays a role in safely loading your vehicle. (GVWR=UVW+NCC)
CCC (Cargo Carrying Capacity) is the GVWR MINUS each of the following: UVW, full water tank (including not water tank), full LP Gas weight and the SCWR.
SCWR (Sleeping Capacity Weight Rating) is the manufacturer’s designated number of sleeping positions multiplied by 154 pounds.
It’s easy to have your vehicle weighted and this will give you the peace of mind that comes from knowing that your vehicle is balanced and properly loaded.
