I have about the same set up and have over 30,000 towing miles. The truck is an F-150 4x4 with E-boost, the TT is a 25 ft. Dutchmen. 5000 lbs. dry weight.
The Blue Ox hitch ball was set by the dealer one inch high before hook up, when both were level. I left the dealer with everything riding level at seven links and instructions to adjust the links when the rig was loaded for the road.
Loaded for the road the CAT scales show a TT weight of 6200 lbs. with 750 lbs. of that weight on the tongue. I find nine links level the rig with just a bit of nose down. I found the Wrangler tires worked fine but wore rather quickly. I inflate the tires to 40 psi when towing.
Cross winds and truck buffets are part of towing. However, in gusts of 35 to 40 mph. I bale out and drive on the side roads at about 30 mph.
It is perfect combo for us. No sway during a swerve or hard stops. No issues in the Rockies or the desert and small enough to wind though city streets to find quilt and gun shops.
Safe travels
