***WE CAN ONLY GET NEW SWIVEL WHEEL TRAILERS, WE CANNOT GET USED*** This unit is the 58DW Tandem Tow which is designed to tow a vehicle behind the Swivel Wheel. The price includes the trailer a spare tire and delivery within the state of Colorado. The ultimate dual wheel transport system for your motorcycle, ATV, golf cart, go cart, etc. The Swivel Wheel Transport System is a new dual wheel design "type" system, available for interfacing with selected tow vehicles and Fifth Wheel travel Trailers with a Class-III or Class-IV receiver hitch installed. The Swivel wheel systems do not include the adverse effects of a bumper pull trailer, which is the ability to jack-knife when backing or fishtailing while driving. The Swivel wheel system will always track with the tow vehicle whether in the traveling mode or backing up. This is especially important when attached to a fifth wheel travel trailer. With other trailers, the second trailer must be disconnected prior to backing the fifth wheel trailer. If the circumstances are just right, this tends to be a major problem. When the fifth wheel trailer is backed up with the Swivel wheel system attached, the Swivel wheel system tracks in a straight line with the fifth wheel trailer. No need to remove the Swivel wheel system to back up. The Swivelwheel-58DW (Dual Wheel) system has a weight capacity of 1200 pounds. This is sufficient for transporting the majority of the large motorcycles on the market, as well as ATV's, Electric & Gas Golf Cart, riding lawn equipment etc. The Swivelwheel-58DW system incorporates two swivel wheel assemblies with torsion suspension designed by Fast Master Products, Inc. and manufactured to specification by a leading torsion suspension manufacturer. The wheel assembly is a 5.70-8, "D" Rated, 6-Ply, highway speed trailer tire. This tires have a load rating of 1075 pounds at 100 PSI cold inflation. With a system weight capacity of 1200 pounds, the tire will never see a 2150 pound load. The front deck height on all Swivelwheel systems is adjustable to accommodate the receiver height on the tow vehicle. The deck is 3/4" treated/painted plywood. This two wheel trailer is available for various transportation needs. A self locking wheel chock is available for motorcycle transportation (included at additional cost). Contrary to popular belief in some chat rooms, the Swivelwheel systems do not include the perceived caster flutter while driving down the road at any speed. The swivel assembly design was engineered to remove the (as we call it) shopping cart caster flutter syndrome. This is true with a loaded or empty deck, as well as at city or highway speeds. The systems also include an adjustable friction pad and rotor assembly to alleviate any chances of flutter in the caster assembly. This Swivelwheel system comes with front removable jack stands with wheels for ease of moving around while disconnected from the tow vehicle. A frequent question asked is if the Swivelwheel system is legal to tow in all states. There are basically 22 states that do not allow double trailer towing, which some call "Triple Towing". These states are the entire east coast from Maine to Florida, Oregon and Washington. The Swivelwheel system is considered to be an extension of the fifth wheel chassis frame. It is not consider to be a trailer. The system cannot jackknife or fishtail. It is not like another ball mounted trailer swinging from side to side. Some states may not have that same view. Always check with the states that you are traveling through for details. There are numerous web sites that will give you state by state information in regards to towing laws.
