Practice & Patience are key
I tow a 34ft twin outboard Pursuit between ATL and whatever destination I'm headed. She's 13K lbs loaded with everything and I have her on a triple axle Myco trailer. As several others have said, keep looking well down the road, watch for potentially challenging situations and plan ahead. I always tow less than 75mph and keep an eye in your mirrors because problems can come from behind as easy as in front. The biggest impact you can have is practice and stay patient.
