I'm new, not sure if this is the way or place to ask, but some 'experts' are subscribed here so please help. I have a 2005 5.4L gas, auto, F-150 ext cab long bed. The dealer said it had a F-250 axle, 10 ply tires, and can carry 7700 lb load payload. I have a 5th wheel hitch and gooseneck dump trailer to haul, carrying a dump trailer on it, so that's about 8000 lbs empty. Stacked trailers saves on transportation expense, it's a 1100 mile haul and that's what I need to do. Towing 8000 lbs, is it safe as described, although it says F-150, it seems every time I go in for an oil change, the service department tells me how heavy duty "this" truck was ordered. GVWR on the door might give me more info? By the way, it's on I-10, flat, sea level, easy ride.
