I have about 1500 miles on the combo below (my first) with no significant issues, but would like to get some experienced forum input on my TV capacity versus trailer. I have not had issues yet, but would not pull anything larger with this truck due to "fatigue" of driving long distances.
*Primary question- Is this combo within limits?
*Secondary - How many people would be comfortable with this combo?

I plan to hit the scales the next time I am loaded to confirm weights, but this is the best info I have to go on now.

TV - 2017 F150 Supercab 3.5 EcoBoost with tow package
-Axle ratio - 3.55, Wheelbase 145"
-Max trailer weight 12,000 lbs
-Max Payload 2050 lbs (corrected)
-GVWR 6900 lbs, (GCWR) 17,100 lbs
- Normal passengers and payload probably 900-1000 max

Trailer - 2015 Cougar 21RBS
-Length 26'
-Dry weight 5238 lbs
-GVWR 7200 lbs
- Hitch weight listed as 580 lbs, but I assume up to 900 lbs
Weight distribution hitch and two sway bars, although typically only use 1 for routine driving (normal wind)
