Are you talking a full sized Chevy Blazer with a V8, or a S10 Blazer with a V6? That will make all the difference. A compact SUV like an S10 Blazer is not designed (regardless of the towing capacity) to haul that much. While it might do it in an emergency, your transmission would be needing replaced quick!
I do like load distribution bars, when used correctly. Problem comes when a truck that weighs 3100lbs try's to stop a 6000lbs trailer. Not that brake fade isn't a serious issue. But the problem lies in when the trailer pushes a truck and unloads the rear axle. In this situation load distribution bars make it worse. Causing a loss of traction or even just stability. Very real reality is headlights touching tail lights.
But all this depends on a proper setup and driving. The trailer should stop the truck, or at least do most of the stopping. Anyone heard of a Johnny bar?
