A trailer is a large compartment attached to a truck that is used to store different goods. It is detachable from the truck.
Can I Leave My Trailer Attached To My Truck? You can leave the trailer attached to the truck, but not for more than two days. It allows the trucker to sleep and take a rest. But it can damage the suspension electronic appliances and drain the battery.
People who are more conscious about the functionality of the vehicle’s part prefer to unhitch the trailer. Well, in my opinion, it is better to do so to keep the truck functional for a longer period and avoid spending hundreds of dollars on maintenance and repair.
For how long can I keep the trailer attached to the truck?
A semi-truck consists of a tractor and a trailer. Both compartments are attached through joints. You can detach the trailer when not in use.
Should I keep it attached or detach it when the vehicle is not in use? There is a difference of opinion about this question. Various people separate it from the truck; some prefer to keep it attached.
There is no problem in keeping both parts attached overnight. You can even keep them hooked for two to three days. Keeping them hooked longer than that can cause serious issues in the vehicle.
What are the benefits of keeping the trailer attached to the trucks?
Trailers are used to carry heavy loads from one place to another. They are usually packed with different goods, and drivers drive long distances to deliver them. Tiredness and inadequate sleep are the main reasons for late-night accidents.
The truckers drive late at night for 2 to 3 days in hilly areas to reach their destination. Taking short naps during long journeys is crucial for all drivers. Keeping the trailer hooked to the vehicles gives them a better place to rest and enjoy a sound sleep.
Detaching a trailer is a tedious and time-consuming process. So, it is preferred to keep them attached to save time. Unhooking trailers also produce a lot of noise that can disturb the neighbors. So people prefer to keep them hooked to avoid all these troubles.
What are the drawbacks of keeping the trailer attached to the truck?
Besides its benefits, keeping the trailer attached can cause many problems. Here is a brief description of all of them.
Damage to suspension and shocks
Each trailer has a specific tongue weight, which is the downward weight applied by the trailer on the vehicle. The downward force will be high if it has a higher tongue weight.
The suspensions and shocks of the trucks remain in stress. The heavy load accelerates the wear and tear in the vehicles’ suspensions. The wheels and other parts can also get damaged due to prolonged exposure to stress.
The tongue weight is zero if a trailer is completely balanced with the truck. But it can not happen as each type has some value of tongue weight. All of them can cause damage to the suspension systems.
Drain truck battery
The trailers are powered by the trucks’ batteries. The batteries deliver a DC current to run all the appliances in this compartment.
It usually happens in old models where power is delivered from the truck to the storage compartment. Keeping them attached for a longer period can drain their battery.
But modern-day vehicles do not possess this problem. They have a system to cut off the power supply of the trailer when the ignition is off. In these vehicles, keeping both parts hooked will not drain the battery.
Occupy more space in the parking lot
They are large vehicles with lengths ranging from 70 to 72 feet. Parking such a big vehicle is a difficult task for all drivers. The drivers detach the storage compartment to occupy minimum space in the parking lot.
Parking trucks with trailers can create space problems for other vehicles. There will be a shortage of space for other automobiles. Another problem arises when parking it on a roadside or in populated areas. You can not park it anywhere.
You have to consider the location and traffic flow before parking it. Detaching it allows us to drive to any place when not towing any weight. Hauling both compartments to all places will be a problematic task.
It is also vulnerable to damage if parked for a long time in unknown areas. So it is advisable to separate it from the truck when not towing the load.
Damage to the electronic appliances
Level and even surface are essential to keep the trailer hitches to the truck. The storage compartments also have appliances like refrigerators to store all the edible and temperature-sensitive items. If the ground is not even, the propane system in the fridges will not work correctly.
You can drive it to the grocery store to buy all the stuff by unhitching the trailer. It will save the time and fuel present in the vehicle’s tank.
Tips to follow to minimize the damage caused by keeping the trailer hooked to the truck
Keeping the trailer hitched to a vehicle is not that bad. You can leave it attached to get all the benefits on certain occasions.
Ensure the connection between the trailer and truck is safe and stable before hitting the road.
Park the pickup on an even ground and use stabilizer jacks to avoid the jiggle. Unplug all the electric appliances and turn off the ignition to turn off the electric supply.
Keep the tow weight within the limits to avoid damage to the suspensions and shocks.
You can also secure the wheels to avoid unnecessary movements while sleeping in it.
