Is it possible that the trailer is a 25QB? I haven't been able to find specs on a 25QH. That's a hefty trailer for most F150s. What's the truck's payload? It's on the sticker on the driver's door.

Taking it to the scale is the way to know exactly what you have. Find one here:

One all hooked up with WDH bars cinched up, one hooked up with the WDH bars disconnected, one with the truck only. First weigh costs around $11, reweigh costs $2 each, so $15 total.
These weights will give you this info:
