Is this TT too much for my '15 F150?

I have a LaCrosse 329 which is a little heavier than the 318 and towed it for a very shot time with a 2014 GMC 1500 before upgrading trucks. The 5.3 in the GMC had adequate power to pull it and stop it, but keeping it stable on the highway around big trucks and their wakes was another story. Ended up moving up to a Ram 2500 and with the same hitch it tows very well up to about 30 mile an hour side winds. Above that you have to tighten the snot out of the friction bars. I also have a friend with a 318 and he pulls it with a Ram 2500 too. I think it comes down to weight and stiffness. My Ram weighs 8500 pounds with the Ranch Hand bumper, headache rack, and tool boxes, and right at 10K when you add in people, dogs, and trailer tongue weight. The 1500 was probably at 7000 pounds loaded the same way. I would much rather have my tow rig out weigh my bumper pull trailer than the other way around.
