towing V20 w/explorer

Hope you guys are still following this thread! ???

Rap...I sent a query to Wellcraft re: the weight of my boat and they came back with a dry weight of 3120 lbs! I have a duel axle Load Rite that seems very heavy to me...I figure I gotta be pushing at or past 5k with boat, trailer and gear.
The trailer HAD brakes but they are now hunks of rust that serve as nothing more than ballast!
