I used my Tacoma with the Teconsha P3 today. Reading the adjustment directions it said to continue to increase the gain number from 6 until the trailer skids when using the manual brake control. It took until setting 9.5 or 10 before the my Coleman Niagara would skid. Does that seem high? On my initial drive using setting 6 the temperature of the brakes was only 85. At setting 9 later the temp was 195. The trucks brake temp was 190 each time.
