I just re set my gain on my trailer, I was running at about 7.0 but every time I did a Hub/brake heat check my trailer hubs were a bit warmer than I wanted,, I backed off to 5.0 and didn't notice any change in brake feel but did notice my hubs were running allot cooler. I have discs all the way around and feel that I am right where I need to be,, The truck does not feel as though its being pushed and upon a good hard brake I can feel the trailer brakes pull and help out.. So its just going to take getting used to what works for you,, Also,, I use Tow/Haul anytime the trailer is hooked up and just love the way the transmission helps slow me down. If you have it use it!
