Check the owner's manual. It is the starting point for determining what features your truck has, such as a towing package. The manual also will help you locate compatible hitches for your truck. If your RV is wider than the truck, you might be required to install extended side-view mirrors. The owner's manual will have a list of optional equipment available for your vehicle.
Choose the correct hitch. According to NHTSA, trailer hitches are rated according to load capacity and tongue weight. Load refers to the gross trailer weight, and tongue weight refers to the downward force applied to the hitch ball on the truck. Again, the owner's manual should identify the correct hitching system for your vehicle. Most trucks come equipped with a Class III hitch, which can tow an RV up to 5,000 pounds.
Visit the Department of Motor Vehicles (DMV). Every state has different requirements with regard to towing an RV. According to the Edmunds website, "At a minimum, all trailers need to have working taillights and brake lights, and most states require registration of the trailer or RV beforehand." Knowing your DMV regulations will prevent any unnecessary hardships down the road when you tow an RV with your truck.
Install safety chains. According to the NHTSA, most states require safety chains to be attached to the hitch system on the tow vehicle. The safety chains can be secured to the trailer hitch by crossing them underneath the coupler. The chains should allow enough room so the RV safely turns with the truck, but tighten the chains so they do not drag along the road.
Check tire inflation. The rubber meets the road, and you must ensure that both your RV and your truck tires are properly inflated. Again, check the truck owner's manual, and always follow the manufacturer's recommendations for proper inflation. Under-inflated tires on either the truck or the RV can cause the RV to sway, and that could cause a serious accident.
