First off, thanks for all the input from everyone, I'm sure we can figure this out, if it takes till spring when I start hauling again! Yes, it is the Hopkins Agility model. It is set up straight within the truck, with the tilt about level front to back. I installed using the factory harness from my 2004 GMC truck mated with the harness from the controller. Maybe I should pull it out and double check wiring configuration, seems it was very straight forward and hard to screw it up. Brakes work VERY well when applied manually, seems this indicates system works, just not like it should. Both settings are set to max, should almost lock brakes up, right? BTW, this is a Carri-Lite, weighs about 10,000 lbs or so, all 4 brakes recently adjusted. System has behaved like this since first installed over 2 years ago. Maybe I'm expecting too much, just feels like I have to use a pretty heavy pedal to slow down. Thanks again everyone, Larry
