And what should the numbers look like for a correct hook up? Front axle weight about the same as unhooked?
When you hitch up your trailer, some weight is lifted off the front axle.
Since 2011 Ford has recommended for its trucks that you only return half of that weight. Equal-i-zer and others suggest that you return between 50 and 100%. Everybody now says do not add any additional weight beyond that.
These recommendations have changed over the years based on some studies done by the SAE and the RV industry.
