Just my 2c worth, when looking at the towing capacity of any vehicle, calculate 80% of that to determine the max weight that can be towed. This compensates for a host of conditions, going up hill, weight of passengers etc. When calculating the weight of what you will be towing, add in the weight of items being packed in. Food, clothing, water, propane. We have a 32' travel trailer and add 1,000 pounds to the delivered weight of the trailer.
