First, check your owner’s manual to answer these questions:
- Is your vehicle designed to tow?
- If so, what is the maximum amount that you can safely tow?
If the answer to the first question is “yes,” then here is our overall recommendation:
- If your vehicle’s owner’s manual provides recommendations for severe-duty use, towing qualifies – and you should follow these guidelines carefully.
- This will include checking vehicle components and replacing them more often than is typical.
- Do not exceed maximum towing limits. When exceeded, it’s more likely that you’ll damage your vehicle and/or get into an accident.
If you plan to modify your towing vehicle to give it extra power or additional safety features, check your warranty. Will making these modifications void any warranties? If you’re purchasing a new vehicle to tow, ask the dealership about any towing or camping options that will be covered by the manufacturer’s warranty.
Also note that, even if you increase your engine’s power, this does not increase the maximum amount that can be safely towed by a particular vehicle.
Here are ten specific items to check each time you’re getting ready to tow (note: these are not being presented as the ONLY items that you should check, only some of the most important):
Test your brakes thoroughly before each trip. When towing, you need more stopping distance and so having brakes that are even slightly worn could be a hazard. When you’re towing, don’t ride the brakes; if you do, then you might overheat them and/or jackknife your vehicle. When driving downhill, drive at a reduced speed, using your brakes as necessary.
If you’re towing a trailer, some come with their own braking systems that need to be connected to your vehicle. Although it takes added skill to coordinate the braking systems, this system means less stress on the towing vehicle’s brakes.

2. Cooling system
Proactively prevent a meltdown. Your vehicle will get heated up by pulling an extra load so your cooling system needs to work optimally to safely tow. So, add the following to your checklist, replacing worn parts:
- Radiator, including hoses and fluids
- Water pump
- Thermostat and housing
- Cooling fan and its switch
3. Hitching devices
Check the hitch ball regularly to make sure that it hasn’t loosened and is still firmly attached to the draw bar. Make sure that the coupler and hitch ball fit together snugly, and ensure that any tow bar used is parallel to the ground when the towed vehicle is attached.
Each piece of towing gear comes with towing capacity limits. Double check that the equipment you have is suitable for what you plan to tow.

4. Safety chains
If your trailer becomes unhitched when you’re towing, the only thing keeping the two vehicles together will be your second line of defense: your safety chains, which are required.
Make sure that the chains you use are sufficient for whatever you’re towing. Light-duty trucks often use 5/16-inch thick chains, while medium-duty trucks often use half-inch thick chains, with heavy-duty trucks using 5/8-inch thick chains. When choosing what thickness to use, make sure that they will help keep the trailer from drifting, while still allowing it to turn easily with your towing vehicle.

5. Springs and shock absorbers
Consider adding heavy-duty springs and the best shock absorbers you can buy and make sure that they are in good shape before each tow. Lighter-duty shocks can cause the towing vehicle to sag in the back while heavy-duty versions will help to keep your vehicle stable and level while towing. As a side bonus, they’ll also make the ride more comfortable.
Be sure to also check your hub bearings when doing your suspension check. While small in size, they can cause major problems when not optimal. If one falls off, the wheel can flip flop around, damaging the brakes and potentially even causing the wheel to become disconnected from your vehicle.
Tires with the correct load rating and proper inflation are important. A common mistake that people make is to check the tires on the truck that will be doing the towing – but not the tires on, say, a camper or trailer that is being towed. Do you have a spare tire for both your truck and for whatever you’re towing?
Blowouts are doubly dangerous when they occur during towing. If this happens, stay calm and get off the road as quickly as is safely possible. Here are tips for quick tire repairs to get you to the shop. Also find tire gauges, cleaners and more.
Perhaps your truck came pre-wired for trailer towing from the factory or maybe your pre-installed hitch already contains the necessary connector. Whether one of these is true or whether you needed to do your own trailer wiring, you need to make sure that nothing has short circuited before you tow.
And, even if you’ve just bought a new truck, one pre-wired for towing, you will still need to double check that the wiring is adequate enough to run both your truck lights and the trailer lights. You can’t always count on that to be true.
Visibility can be a challenge when you’re towing something behind you. You can’t see the other vehicles as well, and they may not see your truck as well, either. Lights, including brake lights and turn signals, are even more crucial in these circumstances, so make sure that all are in good working order.
Consider using extended towing mirrors for increased visibility. You can choose replacement mirrors or wide-angle clip-on mirrors, so test options out to see what works best. Extended mirrors are especially valuable when towing a wide vehicle.
Note: because you’re carrying a heavier load, it will take longer to accelerate so be very aware of that if planning to pass another vehicle. Here are options for your towing mirrors.
Check and replace fluids more often, including motor oil. The added weight inherent in towing adds stress to the towing vehicle, causing it to run hotter than normal.
Choose products carefully. Synthetic oil, although more expensive, has no carbon—and therefore can’t leave carbon deposits on your pistons or in the combustion chamber as regular motor oil can. It also makes sense to use synthetic transmission fluid.
Also check and change filters often for optimal performance.
Bonus towing information:
The most important element in safe towing is you, the driver, so make sure that you:
- Get enough rest before starting to tow
- Feel confident backing up while the object being towed is attached; practice before starting on the road
- Take breaks when necessary to rest if going for a long haul
- Take turns more slowly when towing
- Leave enough safe distance for braking
- Have a fully stocked emergency kit with you at all times
- Have the right hand tools, specialty tools and work gloves that you need for unexpected repairs
