IIRC every dealer should have a booklet for thier trucks that lists every possible camper loading situation. I obtained one from Dodge years ago. If you get one of these for your Ford, you could look for a truck model with wheelbase, engine, transmission etc that closest resembles your truck in order to get an idea of the specifications.
My truck has the snow plow prep option which does not allow a camper package, hence I have the dubious "not recommended" disclaimer sheet. But I was able to find an almost exact TC loading diagram for the same options as my truck for the camper optioned truck to compare.
