K5-Z71 is right and he also mentioned adjustable hitch which is the best option. Even if you are only towing one trailer it usually takes hooking up and measuring. Eyeballing works but using a level is best. Rarely will you get it right first try. With my Tahoe it took a couple hook ups and the adjustable hitch made it a lot easier.
Here’s a picture of the adjustable hitch I got off Amazon that works well and it has a lock as well as 2”/2 1/2” ball.
Trailer is double torsion axle with 14” wheels. The boat and trailer are around 6,500 lbs. Tahoe has air suspension and the trailer infotainment is really nice for checking lights and trailer status.
The truck doesn’t matter it’s the balance of the truck and trailer that is important! Different trailers might require different drops but all will tow the best if level and balanced. I like to go slightly more than the recommended 10% tongue weight but a level trailer is the most important part.
