Need help with the numbers on the weights and such

Hey all, long time listener, first time caller.

We are looking at buying a TT and I admit I feel overwhelmed with all the numbers floating around in my head. I am a family of 5 and want enough room for everyone to have their space but I'm concerned about my TV and the limits of it. I don't know if I'm shopping too big or if my vehicle can handle the weight. If someone can put it in layman's terms that would help me a lot cause I just can't seem to wrap my head around all the different numbers and acronyms...

I have a 2010 F150 FX 2 sport with the tow package. The engine is a V8 5.4L 3v. I've looked on the 2010 tow rating guide and it has 3 options for the 5.4l. 8400, 9700, or 11300. It appears this is dependent on it being 3.15:1, 3.55:1 or 3.73:1. I don't know what my truck has. When I've researched for it, i only find it to be 3.55 so I'm assuming that's what I have, which would then put me at the 9700lb rating. my GCWR is 7100 it says the combined occupant and cargo weight liming is 1637lbs. I'd say my family weighs 575

Will someone please explain the math I need to do to figure out how heavy of a trailer I can get? I have a hard time keeping the numbers straight and I don't want to buy too big.

Thanks all!!!
