Finding an RV with the perfect floorplan is exciting, but before you start planning your first trip, there is one important question to answer: Can your vehicle safely tow it?
Towing capacity can feel confusing, especially when you begin seeing terms like GVWR, UVW, payload, and tongue weight. Each number tells you something different, and looking at only one of them may not give you the full picture.
Understanding a few basic weight ratings can help you shop more confidently and choose an RV that is a good match for your specific tow vehicle.
Towing Capacity Is Only Part of the Picture
Your vehicle’s towing capacity is the maximum amount the manufacturer says it can tow when the vehicle is properly equipped. While this is an important number, it should not be the only rating you consider.
Two trucks that look nearly identical may have very different towing limits based on their engine, transmission, axle ratio, cab configuration, bed length, drivetrain, and installed towing equipment. That is why it is important to check the ratings for your exact vehicle rather than relying on a general number you find online.
You can usually find helpful information in your owner’s manual, on the labels inside the driver’s door, or through the vehicle manufacturer using your VIN.
What Is Payload Capacity?
Payload capacity refers to the amount of weight your vehicle can carry, not pull. This includes the driver, passengers, pets, tools, coolers, luggage, aftermarket accessories, and the weight the RV places on the hitch.
Payload is commonly overlooked because a vehicle may have enough advertised towing capacity for an RV but reach its payload limit first.
For example, if a truck has a payload capacity of 1,500 pounds, every person and item placed inside or on the truck counts against that limit. The RV’s tongue or pin weight also counts toward it. Once everything is added together, the available payload can disappear more quickly than expected.
The payload label inside the driver’s door is one of the most useful places to begin because it applies to that particular vehicle as it left the manufacturer.
Understanding the RV’s UVW
UVW stands for Unloaded Vehicle Weight. You may also hear it called dry weight.
This is generally the weight of the RV as manufactured before you add your camping supplies, food, clothing, water, and other personal belongings. Depending on how the manufacturer lists its ratings, certain dealer-installed or aftermarket equipment may not be reflected in that number.
UVW is helpful when comparing RVs, but it should not be treated as the actual weight of the camper once it is ready for a trip. Your RV will weigh more after it is loaded.
What Does GVWR Mean?
GVWR stands for Gross Vehicle Weight Rating. This is the maximum the fully loaded RV is rated to weigh.
The GVWR includes the RV itself along with everything added to it, such as food, clothing, cookware, camping equipment, propane, water, and personal belongings. The RV should never be loaded beyond this rating.
When determining whether an RV may be appropriate for your tow vehicle, GVWR can provide a more conservative number to consider than dry weight because it accounts for the possibility of the RV being fully loaded.
What Is Cargo Carrying Capacity?
Cargo carrying capacity, often shortened to CCC, tells you how much weight can be added to the RV without exceeding its GVWR.
Camping gear adds up faster than many people expect. Dishes, food, bedding, outdoor furniture, tools, grills, bicycles, and full holding tanks can all add significant weight.
Water is especially important to consider. Fresh water weighs a little more than eight pounds per gallon, so traveling with a full tank can add several hundred pounds depending on the size of the tank.
You may not always travel with full tanks, but their potential weight should still be considered when deciding how the RV will be used and loaded.
Tongue Weight and Pin Weight
A travel trailer places part of its weight on the vehicle’s hitch. This is called tongue weight. A fifth wheel places weight over the truck’s rear axle through the fifth-wheel hitch, which is commonly called pin weight.
These weights matter because they count toward the tow vehicle’s payload capacity.
The listed tongue or pin weight is often based on the RV before it has been fully loaded. Once batteries, propane, supplies, and personal belongings are added, the actual hitch weight can change. Where those items are stored inside the RV can also affect how that weight is distributed.
This is one reason payload capacity is especially important when shopping for a fifth wheel. Even if a truck has enough towing capacity for the RV’s total weight, the pin weight, passengers, hitch, and cargo may exceed what the truck is rated to carry.
Do Not Forget the People and Gear in Your Vehicle
It is easy to compare the RV’s weight with the vehicle’s towing capacity and assume everything works. However, the items inside the tow vehicle also matter.
Passengers, pets, car seats, toolboxes, coolers, fuel containers, and bed covers all add weight. The hitch itself also has weight and must be included when considering payload.
If you regularly travel with several people or carry equipment in the truck bed, calculate those items based on how you will actually travel. Planning around an empty vehicle does not provide an accurate picture if it will normally be packed for a family camping trip.
Look at the Entire Towing Combination
Other ratings may also apply to your towing setup. These can include the Gross Axle Weight Rating, or GAWR, and the Gross Combined Weight Rating, or GCWR.
GAWR is the maximum weight each axle is designed to support. GCWR is the maximum allowable weight of the loaded tow vehicle and loaded trailer combined.
The vehicle, RV, hitch, tires, and other towing equipment must all be properly rated for the load. The lowest applicable rating becomes the limit, even if another component is rated to handle more.
How Can You Find Your Vehicle’s Ratings?
Start with the information provided for your exact vehicle. Helpful places to check include:
- The labels inside the driver’s door or door frame
- The vehicle’s owner’s manual
- The manufacturer’s towing guide
- The manufacturer or dealership using your VIN
Avoid relying entirely on an advertisement or a broad online search. A manufacturer may advertise the maximum towing capacity available for a certain model, but that number may only apply to a specific configuration.
If you are unsure, contact the vehicle manufacturer or an authorized dealer and ask them to verify the ratings for your exact VIN.
Bring Your Vehicle Information When You Shop
When visiting Crabtree RV Center, bring as much information about your tow vehicle as possible. Your VIN, payload label, owner’s manual, and details about your usual passengers and cargo can all help us narrow down your options.
