The towing capacity of a truck can be found in the owners manual. Depending on the year, model, and make of the vehicle, towing capacity varies. If the vehicle does not have an owners manual, one may be found online; most of the time free of charge. An alternative may be to search for the vehicle information on the internet and see what the manufacturer website says about towing capacity. If the
. owner is unsure of the year and model of the truck, the vehicle identification number that is located on the dash board and drivers side door frame can be used to identify the vehicle.The condition of the vehicle also greatly affects the towing capacity. If the vehicle is an older model and has not been taken care of properly, the towing capacity lessens due to several factors. If the engine has not been properly cared for, it can not handle the extra weight of the tow. If the body of the truck has not been properly cared for, rust can weaken the body and therefore do serious damage when one attempted to tow a trailer or haul a heavy load.Different makes of trucks can handle different tow loads, depending on the structure of the vehicle and size of the engine. Trucks with hemi block engines can handle a lot more strain than a standard 8 cylinder engine; however, 8 cylinder engines are not wimpy by any means. The best trucks to pull heavy loads with are those that are equipped with an all-wheel drive function. All wheel drive can handle any terrain and stabilizes traction that the vehicle has on the road even more than a normal vehicle does, making towing even more efficient and safe.If any more information is needed regarding towing capacity, visit the local automotive store.
