I hear that. Mine is a 29'er and weighs in at just north of 14000 lbs loaded. Thats light for a big box so we got blown all over the road. Your unit is new enough that you have front and rear anti-sway bars and a front track bar (aka hardpan bar) from the factory. Since Ford does not know what the coachbuilder is going to plunk on the chassis, they ship all the units with the anti sway bars set to "soft". The first thing you can do is move the links to the inside hole (aka hard) position. This will cost you zero unless you choose, as I did, to install Hellwig adjustable links on the front so you don't get the occasional clunking noise. They are under $100.
The next freebee is tire pressure. It is important! You have to weigh to do it right.
In my opinion, the next task is the rear track bar. Most folks opt for the BlueOx as it is high quality. You Will need a 250lb torque wrench for this install. I also used a lasar to line up the bar to the frame. This will stabilize the rear axle and eliminate "tail wag". Important if you are towing.
All these enhancements/adjustments have an incremental effect on your driveability. They are fairly inexpensive and a DIY project if you have skills and tools.
A good truck shop front end allignment may help as well.
BTW, I started with the safetplus too.
If you are stll not satisfied, you can try Koni Shocks and Rear air bags next. I did not need them. Now I can stay in my lane during truck passes with ease. I hardly notice anything smaller. No tail wag noticed while towing even with a very light toad that is skittish in the wind. After a full day on the road I am not beat when we pull into the park for the night.
I can drink my coffee without spillage. My DW can make it to the jon without a pinball impersonation. Ahhh.
