How Much Safety Margin to Allow...If Any?
Hi Everyone, We have a 2011 Ford Expedition 4x4 with the Heavy Duty Trailer Tow package. A few relevant specs: Axle = 3.31 Max Loaded Trailer Wt = 8,900lbs GCWR = 15,000lbs GAWR Front = 3,70...

Trailer tongue load weight should be 10-15% of total loaded trailer weight. Make sure vehicle payload (reduced by option weight) will accommodate trailer tongue load weight and weight of passengers and cargo added to towing vehicle. Addition of trailer tongue load weight and weight of passengers and cargo cannot cause vehicle weights to exceed rear GAWR or GVWR.
So you can tow up to the the first limit you hit. When it comes to RVing, rarely is that the vehicle's tow rating and GCWR.
If you have the HD towing package in the Expy, you get the 3.73 axle.
Your RV limit is likely payload or the 900-ish pound tongue weight limit. 900 pound TW means about 7k loaded TT, or 6k dry.
