Result Details
You can use this calculator to:
- Work out if your truck can tow a given RV
- See the heaviest RV your truck can tow
- Work out how much payload you have left once your RV is hitched
- See how close you are to limits such as GVWR, GCWR, etc.
- Understand generally your RV weights
The calculator assumes you are familiar with terms like GVWR, GCWR, UVW, etc. If you’re not, then please read the "Acronym Definitions" section first.
Disclaimer: It is your responsbility to check all formulas, numbers and data for accurate information. Also check the load capacity of your tires. This calculator does not include Gross Axle Weight Rating (GAWR). Make sure you check your axle ratings and compare to your scale. The developers of this calculator are not liable for any inaccuracies and this calculator is not meant to replace or override the suggestions of professionals. Please drive safely and happy camping!
Formulas
[1] Truck Curb Weight = Truck GVWR - Payload Capacity
[2] Towing Capacity = GCWR - Truck GVWR
[3] RV GVW = RV UVW + Cargo Weight
[4] RV Payload Capacity = RV GVWR - RV UVW
[5] Truck GVW = Truck Curb Weight + Passenger Weight + Cargo Weight + Hitch Weight
[6] GCW = (Truck GVW - Hitch Weight) + RV GVW
[7] Hitch Weight = Hitch Weight Percentage * RV GVW
Acronym Definitions
Curb Weight: The total weight of your vehicle apart from any passengers, cargo or non-factory items. Curb weight does include the weight of gasoline, oil and other fluids necessary for operation. You can think of curb weight as the weight of your vehicle, as it sits parked at the dealership.
UVW: Unloaded Vehicle Weight, sometimes referred to as “Dry Weight", is the weight of a vehicle with maximum capacity of all fluids necessary for operation of the vehicle, but without cargo, occupants or accessories that are ordinarily removed from the vehicle when they are not in use. This number can be found on a sticker from the manufacturer. The only way to get an accurate UVW is to take your vehicle to a weigh station and weigh it empty.
Truck GVWR: The total weight that the truck is designed to carry. This includes the weight of the truck, driver, passengers, cargo in the cab and truck bed, hitch and tongue/pin weight. Generally this is found on a sticker on the doorjamb.
RV GVWR: The maximum permissible weight of the RV when fully loaded for travel. This includes the Unloaded Vehicle Weight, all fluids, cargo, optional equipment and accessories.
GCWR: The maximum allowable combined mass of a road vehicle, the passengers and cargo in the tow vehicle, plus the mass of the RV and cargo in the RV.
Hitch Weight: The amount of weight a RV's tongue or king pin places on the hitch it is mounted to. This is automatically calculated from the numbers provided above and is an estimate.
Towing Capacity: The maximum weight your vehicle is able to pull while towing, i.e. the weight of a RV, a boat, or another vehicle.
Payload Capacity: The maximum weight that can be hauled inside the vehicle, including driver, passengers, cargo, and the hitch weight. A Payload Capacity is published by the manufacturer, but can be calculated by finding the difference between a vehicle's GVWR and curb weight.
