I have been trailering my 21 Seacraft +/- 4,500 lbs with a JGC, 6 cyl, with a 4 x 4, which is good to take it out of steep ramps. Been at it since 2004, trailer has brakes, dual axle. Never an issue, change the trans fluid everyyear, typical tow is 40 miles round trip, about 7-10 times and about 10-12 trips of 200 miles to the Keys. Jeep has 167,000 miles
