So the GVWR of the truck is 6522 pounds.
What is the model trim of the truck? XE, LE or SE?
Where did the payload number and curb weight you used come from?
The curb weight of the truck is listed by Nissan as 5038 pounds. The problem is that this number is for the "base truck" and not specific for your trim. Without knowing which trim package you have it is impossible to determine what your available payload is.
using the base curb weight, your available payload is just (6522 - 5038) or 1484 pounds
Again using the base curb weight (which is the standard truck with NO OPTIONS, a 150 pound driver and a full tank of gas):
1438 - 100 for the hitch = 1338
50 extra pounds for the driver = 1288 pounds
150 pound wife = 1138 pounds
150 pounds for 2 kids = 988 pounds
miscellaneous gear (200 pounds) = 788 pounds
at 10% loading, your camper can not weigh more than 7,880 pounds.
you still need to stay under your Max CWR of 14650, so the camper can not weigh more than (14650 - 6522) = 8128 pounds.
