My current setup is a '13 GMC 1500 Denali and a 2014 Stealth 1913 Toy Hauler that weighs between 5600 and 7700 depending on load.
The truck has the Integrated Brake Controller and I have tried to set the gain per the owners manual. Part of that process requires manually applying the trailer brakes using the controller only and setting the gain so the wheels lock up, then backing it off slightly. Even with an empty trailer, fully applying the trailer brakes from the controller will only slow us down a little. I can not get the trailer wheels to lock up.
Also, when towing, I don't get that familiar feeling of the trailer brakes engaging when I push the pedal - but the brakes are being applied. Stopping is smooth, the truck stays level and I feel 100% in-control at all times in normal driving conditions. I haven't had to make a panic stop yet.
I have the gain set around 8 (out of 10) - much higher and I can lock up the trailer pretty easily using the brake pedal. This seems high to me, given the relatively light trailer. I've had the trailer checked by the dealer and they said the trailer is fine.
I've towed small cargo trailers (for dirtbikes etc.) using an aftermarket controller in my prior truck (Tacoma) and I'm used to feeling the trailer pull when applying the brakes. I'm also used to being able to fully lock up the trailer wheels with a squeeze of the the afteremarket controller.
Is this the way it should work with the Integrated Brake Controller, or is there something potentially wrong with my setup? How can I check? Should I be concerned that I can't quickly stop the truck and trailer using the ITBC only?
