I really hate to say this but it sounds like the 2280 lbs trailer weight is dry delivered weight, which usually means no battery, LPG, water, etc.
Most states require brakes on GVWR (trailer) of 3000lbs leaving you with 720 lbs. I tow a landscape trailer a lot with anywhere from 1700 lbs to 7000 lbs and even when towing light I would want trailer brakes. I am sure there are plenty of folks safely towing rigs at or near the 3000lb mark without brakes, but I would make certain of my weights and have every advantage available (WD / sway if possible).
