At 9,000lb, your hitch weight should be on the order of 1,100-1,200lb.
That leaves you 300-400lb for everything else in the truck...including passengers.
Also, your rear axle is only rated or 3,800lb. Once you subtract the empty weight off that, you probably only have 800-1200lb left...you hitch weight will eat that up and then some. That means you have to run with pretty much nothing in the truck bed (including a cap or cover).
L3 on the sticker implies a 3.31 axle ratio...not a huge issue if you have a 10 speed tranny but not ideal.
The 3.5 ecoboost is plenty powerful.
You could load it up and take it to a CAT scale to confirm but at the very least, you are pushing this truck to the limits.
1/2 ton trucks come in a wide variety of capabilities and unfortunately you have one that is on the lower end of those capabilities.
