There is no single answer to this question as it depends on your individual needs and preferences. If you frequently drive in adverse weather conditions, then a 4WD truck would be a good investment. Additionally, if you frequently haul heavy loads or need to access difficult terrain, a 4WD truck would be the best option for you. However, if you don't plan on using your 4WD truck for off-road activities or hauling heavy loads, then you may not need one. Ultimately, it's important to consider your specific needs before making any purchasing decisions.
