Brake Rotor Warpage on 2000 Dodge Dakota

I have ABS brakes and do towing with a 15 travel trailer.

With and without the trailer, many times when I depress the brakes I get a shudder.

I previously had the rotors replaced with heavy duty Bendix brand. And had those installed due to the same problem.

I need to know if someone can suggest a brake rotor that is either extra heavy duty or one that will not warp easily?

Is the shutter from warping rotors or are is the ABS activating?
