For the Truck:
2011 F-150 Super Crew XLT 4x2 w/ Ecoboost 3.5L and 3.15 rear
154 inch WB No Max Tow Package
GCWR - 14,000 pounds
GVWR - 7100 pounds
Max Payload - 1760 pounds
Curb Weight - 5340 pounds (as equipped)
Max Trailer weight (Travel Trailer) - 8800 pounds
The Trailer:
UVW - 4372 with a hitch of 532 = % Tongue = 12.2%
GVWR - 7532 with a 12.2% tongue = 919 pounds
Using your numbers for your camper of 6187 pounds loaded
and 544 pounds of gear in the truck (including hitch weight):
The truck will weigh hitched 5340 + 544 + 755 tongue = 6639 pounds
Good To Go!
Camper will weigh 6187 (less than 7532) - Good To Go!
Your Combined weight of 12,826 pounds (less than 14,000) - Good To Go!
So, the good news is you will be "legal" and the bad news is your rear end will make your gas bill high.
