How Much Can My Truck Tow? The Ultimate Know-How Guide

The towing capacity of your truck should exceed the weight of the trailer you're going to tow

How Much Can My Truck Tow? The Ultimate Know-How GuideHow Much Can My Truck Tow? The Ultimate Know-How Guide

By Christina Quiroz

One of the most crucial considerations when buying a towable RV is to ask the salesman “how much can my truck tow?”. If you already have your RV (check out if you need a special license to drive an RV), it’s easy to make towing weight calculations. But if you haven’t bought one yet, you can decide on the towing capacity you want then match the motorhome based on your need.

If you’re a little skeptical on the information that the salesman or manufacturer feeds you since most of them tell things customers expect to hear, check the truck’s towing specs and data plates. Knowing a particular trucks towing capacity will help you weigh if it’s worth an investment.

Okay, first, let’s talk about some terminologies about vehicle specifications that will help you figure out how much your truck can tow.

Towing Capacity

Towing capacity, often called the maximum towing capacity, simply denotes the maximum weight that a vehicle can tow. The figures for this are usually specified by the manufacturer and should be found in the driver’s manual. 

If the towing capacity of the truck isn’t specified, you may ask the manufacturer of its specs then calculate if your needs can be met by the truck’s towing capacity. 

Consider the passenger weight, equipment to be stored, mounted, or carried, and the additional cargo you expect to load into the equation.

Users should never exceed their truck’s towing capacity because it may adversely affect its overall performance, stopping ability, and may damage the drivetrain.

In fact, some trucks with towing hitches have greater towing capacities than the specified figure because it can fit various types of tow vehicles. In any case, always stick to the manufacturer’s designated towing capacity to prevent any damages or accidents.

Gross Vehicle Weight Rating

How Much Can My Truck Tow? The Ultimate Know-How Guide

The gross vehicle weight rating (GVWR) is the maximum operating weight of a vehicle. It encompasses the vehicle’s individual parts as well as its body, chassis, engine, fuel, engine fluids, other accessories, passengers, hitch, and cargo, excluding any trailers or other vehicles that need to be towed.

In essence, it denotes the value the truck can carry when fully loaded. 

GVWR is typically used to designate weight limitations and restrictions. For instance, the curb weight describes a parked vehicle excluding the weight of passengers and cargo while the dry weight does not take into account the value of fuels, oils, and other consumables. 

Gross trailer weight rating, on the other hand, specifies the maximum weight of a trailer the truck can tow while the gross axle weight rating denotes the allowable weight on any of the truck’s axles. These ratings are all established by the truck’s manufacturer.

Gross Hitch Weight Rating (GHWR)

The trailer connects to the truck through a hitch, consequently putting weight onto the truck’s back; thus, it has to be accounted for. The gross hitch weight rating is the largest weight of the trailer’s load forcing itself on the hitch ball, carried by the rear axle. 

In connection to this, the maximum tongue weight (MTW) is the largest load a bumper-pull (e.g., pop-up campers, travel trailers) can push down the tow vehicle’s hitch. For bumper-pulls, about 13-15% of the camper’s total weight is sufficient for the RV. 

Likewise, the maximum king pin weight (MKPW) is the largest allowable weight the fifth wheel trailer can force down on the hitch attached to the vehicle. Generally, 20-25% of the camper’s weight pushes down the fifth wheels.

Gross Axle Weight Rating (GAWR)

Again, the gross axle weight rating (GAWR) is the largest allowable weight a vehicle’s axle can support. In connection to this, the actual weight carried by the rear axle or the rear gross axle weight, can be figured by calculating the total wheel weight resting on the rear axle, excluding any trailer load on that axle.

The rear gross axle weight rating, on the other hand, is simply the maximum allowable weight you can load into the truck’s rear axle.

For drivers to be able to tow their trailers safely, their trucks must have sufficient engine power for pulling the load. As a rule of thumb, the weight of any trailer should never exceed the tow truck’s maximum ratings or else, overloading will occur.

You’ll know you’re overloaded if the truck becomes challenging to steer and there’s the lingering presence of trailer sway. 

Overloading of RV trailers will ruin the engines, hitches, transmissions, bearings, etc.  Also, it’s crucial to have your rig weighed to make sure you’re driving safely.

Conclusion

The easiest approach to know how much a truck vehicle can tow is to look at the vehicle’s towing capacity. 

Otherwise, you may look at the vehicle’s gross vehicle weight rating (GVWR). It tells users the maximum weight the tow vehicle can handle

Take note of the GVWR then subtract the total weight of the truck from the scale (via a truck stop). The leftover value tells you how much tongue or pin weight you can carry.
