Knowing about RV TOWING may OBLIGE you to put Your vehicles on a DIET!

It is then an obligation to CALCULATE the RV towing capacity of ALL the vehicles you are going to use.

Do not blindly trust the sales person at the dealership who tells you that the pickup truck that you own, has enough towing capacity to pull the huge 5th wheel trailer that he/she wants you to buy.




  • weight distribution is critical for braking, handling and life of the components like tires, springs, axles, bearings of the vehicles
  • keep the center of gravity low, the heavier items low and forward and the lighter items high
  • inflate your tires at the right pressure. Check them regularly when the tires are cold (in the morning before leaving)
  • secure your cargo so there is no shifting of weight while driving
  • have the toad parallel to the ground with the proper hitch receiver
  • have the proper braking system and operable lights in sync with trailer on your tow vehicle, in respect of the transportation regulations. You normally need a separate brake system if you tow more than 1000-1500 pounds.
  • make sure to have adequate extended side-view mirrors. (a rear vision camera adapted to towing is also a good idea)
  • for sway control, a weight distributing hitch system is recommended for large towable trailers over 5000 lbs on a ball hitch.
  • do not have passengers in a towed trailer or dinghy (car pulled behind a motorhome)
  • check your RV towing connections before going and check again stopping on the road later.

Dry Weight: (DW) (constant)

It is a technical term that refers to the weight of an vehicle without any consumables, passengers, or cargo. It is one of the two common weight measurements included in specifications, the other one being curb weight.

Curb Weight: (CW) (constant)

It is the total weight of a vehicle with standard equipment, all necessary operating consumables (e.g. motor oil and coolant), a full tank of fuel, while not loaded with either passengers or cargo.


It is the maximum cargo load that a vehicle can receive.

Gross Vehicle Weight (GVW):

It is the actual weight of the fully loaded vehicle, including all cargo, fluids, passengers, and optional equipment, as measured by a scale. GVW is determined by weighing the entire vehicle, without a trailer attached. It varies all the time.

Gross Vehicle Weight Rating (GVWR): (constant)

It is the maximum allowable total weight of a road vehicle or trailer when loaded - i.e including the weight of the vehicle itself plus fuel, passengers, cargo, and trailer tongue weight/king pin weight.

Gross Trailer Weight Rating (GTWR): (constant)

It is the total weight of a road trailer that is loaded to capacity, including the weight of the trailer itself, plus fluids, and cargo.

In the United States and Canada, the static tongue load, the weight of the trailer as measured at the trailer coupling, is generally recommended to be 10-15% of the GTWR.

In the United States and Canada, there are four main weight classes of trailer hitches as defined by the Society of Automotive Engineers (SAE):

Class I — rated to 2,000 pounds (907 kg)

Class II — rated to 3,500 pounds (1,588 kg)

Class III — rated to 5,000 pounds (2,268 kg)

Class IV — rated to 10,000 pounds (4,536 kg)

To ensure a safe center of gravity, load all gear as low as possible on the trailer. Never overload the trailer.

The trailer-weight rating is usually found on a manufacturer's plate installed on the trailer tongue. If the weight of the payload exceeds 1000 pounds, the trailer should have its own brake system (electric or surge brakes).

Gross Combined Weight Rating: (GCWR) (constant)

It means the value specified by the manufacturer as the maximum loaded weight of all vehicles combined. ( tow and toads )

Gross Axle Weight Rating (GAWR): (constant)

It is the maximum distributed weight that may be supported by an axle of a road vehicle. Typically, GAWR is followed by either the letters FR or RR, which indicate front or rear axles respectively OR FGWAR/RGWAR

Maximum Tongue Weight or King Pin Weight

The Maximum Tongue Weight (for travel trailers) and Maximum King Pin Weight (for fifth wheels) is the most weight that should be pressing down vertically on the "Tow" vehicle hitch.
