Re: V6 Ford Expl. to pull 21 ft? (New boater)
Tow balls and trailer hitches are rated, usually very visible and stamped into the hitch. Tow balls are rated based on diameter and shank size. At 5000#, you'll need a two inch ball with a one inch shank, NOT 3/4". Also, two inch square receiver is in order. Parts that mate preoperly to that will exceed the 5000# rating too.<br /><br />With a 6 cyl., watch the engine temp carefully, and pay attention to the transmission for burnt smells. A friend just pulled a Uhaul trailer filled with miscellaneous stuff from his returning-home-for-the-summer college student, 4 hours, about 1600# - had trouble with engine and transmision overheating. He also had 6 cyl Explorer. If you're traveling less than 50 mies you'll be OK.
