Your rear axle is a 3.31 gear, so not the ultimate towing gears, but being a 2020 Ecoboost, the 10 speed makes up for the taller gears handily. So that's not an issue.
If I'm not mistaken, the RAWR is artificially low at 3800lbs. I believe all 3.5 Ecoboosts get the 9.75" rear diff, which is, in reality a 4800-5000lb rear axle. Someone, preferably the OP correct me if I'm wrong on this.
Even the factory tires are good for 5000lb rear axle load although I'd look for some heavier tires when these wear out.
You're still good.
