To answer your question, in a word NO! In two words, NO WAY!!
As Stu said, that 8500b is DRY WEIGHT. The loaded weight will be closer to 9500b or 10,000 lb. This means a pin weight of around 2000 lb (20%). Now add 200 lb for a FW hitch. Add the weight of you and your better half. Now add any other cargo to be carried in the truck or bed. THIS IS HOW MUCH WEIGHT YOU WILL BE CARRYING WITH THE TRUCK.
Find the yellow placard on the driver door latch pillar which specifies the maximum weight of passengers and cargo shall not exceed XXXX lbs. and compare this to what you plan to carry, calculated above.
Only about 1% of F150 can pull that load - it MUST be an XL or XLT, reg cab, long bed, 2WD with heavy payload option.
The truck CAN pull a decent bumper pull TT. A TT only places 10% - 12% hitch weight on the truck and WD hitches are around 80 lb. While a 10,000 lb FW places 2200 lb + on the truck (2000# pin + 200# hitch), a 10,000 lb TT will only add 1100 lb+ to the truck (1020# hitch wt + 80# WD hitch).
