I don't know beans about a Dodge, but on a Ford the trailer brake controller (TBC) gain is adjustable. At 10, it will instantly lock up the brakes on anything weighing less than about 12,000 pounds. For my 5,000 pound TT, I usually have it set at 5 or 6 and it works great. For my cargo trailer, when unloaded and grossing about 2k, I set it on 3.
My Owner's Guide includes instructions on how to adjust the TBC gain to match trailer weight so you get max braking force without locking up the tires. I'll bet your Dodge Owner's Guide includes it too.
