Some references call for all the weight to be restored to the front axle and some call for 50%.
I am about 50-60% on my setup and it tows great.
What references? The only one that's accurate is your tow vehicle's owners manual.
Your owners manual should have a spec for this. With GM, you are supposed to measure the front fender before adding the trailer. Then adjust the hitch to bring the front fenders back to stock height.
Other manufacturers specs vary on this. I know Ford's is different for example.
Personally I've driven them when they were 50% and the lack of steering control was just plain scary.
