brakes needed on a enclosed trailer with cycle in it?

Three weeks ago, I installed electric drum brakes on a 3,500 pound rated single axle, torsion suspension, 6x12 enclosed trailer I've had for some time. Virginia does not require brakes, nor inspections, on single axle trailers with gross weight under 3,000 pounds. I installed the brakes because I already have over 3,000 pounds of truck camper on board and wanted the additional safety margin. We returned from a trip to The Keys and Blue Ridge Parkway earlier this week, and I was very happy to have the trailer brakes on some of the wonderfully twisty off-shoot roads from the Parkway and for the crazy, idiot Florida drivers (and I thought Wash., D.C. was bad). It cost me about 200 bucks total for a brake kit with new bearings/seals, a break-away system kit and a 7-way plug for the trailer - plus 20 bucks for a couple tubes of Mobile-One grease. Although I pulled the trailer thousands of miles without incident using lighter weight vehicles like a Ford Ranger, I can see now that I should have put brakes on it a long time ago.
