Towed Tractor Rollover

[4570Man]

My brake controller is adjustable. My 2600 pound trailer needs a lot less brakes than my fully loaded GN. If I forget to adjust the controller after pulling the GN it will lock up the light trailer with very light braking.

I have had several close calls with whipping trailers. Every time it was caused by having too little tongue weight and I was able to regain control by applying the trailer brakes manually. These incidents were all over ten years ago when I wasn't early as experienced towing as I am now. Now I always make sure to load the tongue heavy. From what I have seen the gross weight of the load has little to do with the whipping it is all about the tongue weight though a heavier trailer can sure jerk the truck around more if it gets to whipping. Heaviest load I have pulled with a bumper pull was around 20k(load and trailer)on a pintle hitch trailer behind my dually and it tracked fine but I had about 2500lb tongue weight.

I see people pulling 10-15k travel trailers and toy haulers behind half ton trucks all the time.

I put as much distance as I can between my Cummins and them.

One of them jackknifed just outside of town a week or two ago when we had slight crosswinds.

They never learn.

Somewhat related question. Recently purchased an 18' 7K trailer. When adjusting the brakes according to the manual I could never get them to lock up, even with the gain set to 10 (highest setting).

Am I not hitting the brake pedal hard enough?

More likely a wiring issue. Brakes not wired right, maybe to the wrong terminal on the plug. Bad ground?

Or perhaps the brakes need to be adjusted a little tighter?

On a brand new trailer purchased from a large dealer?

Are they activating at all? Just not reaching the drum? You check for voltage at the truck?
