There are many factors when determining how much trailer towing capacity is available. Each car and truck has a specific amount in which they are able to tow with ease. One of biggest factors is the type of hitch that is mounted on the car or truck. Smaller hitch or one inch receivers cannot tow nearly as much as the two inch receiver. Another factor that needs to be taken in to consideration is
. the type of car, truck and engine that is going to be doing all of the heavy towing. Obviously a large truck will be able to tow much more weight than a smaller car. The engine size has a lot to do with the power that drives the vehicle as well as the amount that is able to be towed. A V10 engine is certainly able to pull a lot more weight than a V6 and a diesel engine is most likely able to pull more than a V10. Since there are so many different types of trailers, each one of them is also a factor when determining the amount of weight that is able to be towed safely. Smaller trailers are not as capable of holding large, heavy or bulky items. Their tongue strength is typically not able to carry nearly as much as a large trailer that is twice its size. Typically enclosed trailers can easy transport much more weight than open trailers, but this is not always the case. Construction trailers are typically open, but they are meant to carry large and very heavy items. When figuring out the right trailer towing capacity, it is very important to read all of the specs that come along with each trailer, the hitch, the mount as well as the information about the vehicle itself. With all of these details in mind, the towing capacity is sure to be known and is definitely going to make the trip a safe one.
