A CURT RV hitch is a trailer hitch designed to mount on a recreational vehicle to tow along a few toys, add extra cargo space or to allow a vehicle to be flat-towed behind the RV. These hitches are manufactured using CURT's quality processes of robotic welding, thorough cleaning and precise finishing. Both our RV trailer hitches and RV bumper hitches are coated with a liquid Bonderite coating and high-gloss black powder coat finish to protect against scratches, rust and UV damage, and both offer a 2" x 2" receiver tube opening to accept a ball mount or other towing accessories. CURT RV hitches are designed to fit a variety of RV styles. With two types to choose from -- an adjustable 3-piece frame-mounted style or a bumper-mounted style -- these hitches mount easily onto the frame using the included hardware. This class 3 RV hitch features a gross trailer weight capacity of 5,000 lbs. and a tongue weight capacity of 500 lbs. It can also be used with a weight distribution hitch for a WD rating of 6,000 lbs. and WDTW of 600 lbs. It is able to fit a frame up to 51" wide. It is excellent for towing a cargo carrier behind your RV, increasing your overall cargo space, or an average-size trailer, such as a utility trailer, boat trailer or recreational vehicle hauler for ATVs, personal watercraft or dirt bikes. This RV trailer hitch is also compatible with a tow dolly or tow bar for dinghy towing a small vehicle (NOTE: Never exceed the lowest weight capacity of any towing component). CURT RV hitches are not just another accessory for your motorhome; they are a dependable extension to help you achieve that ultimate RV experience every time you hit the road.
