How do I tell a 5 on 4.5 hub from a 5 on 5 without pulling the wheel?

For a 5-lug hub, measure from the center of one stud to the far outer edge of the stud skipping one position. A reading of approximately 4.5" indicates a 5 on 4.5" pattern, while a 5" reading indicates a 5 on 5" pattern. You can also verify this by checking your axle tag or product specs

Do I need brakes on both axles of a tandem?

Brake requirements vary by trailer GVWR and the laws where the trailer is registered and operated. Some jurisdictions require brakes on both axles of a tandem, while others have different requirements. Check your local regulations and the trailer manufacturer's specifications before choosing a brake setup

What size coupler goes with a 2-5/16 ball at 15K?

For a trailer requiring a 15K-rated coupler, use a 2-5/16" coupler rated for at least 15,000 lbs. The 2-5/16" measurement refers to the ball size, while the coupler's capacity must meet or exceed the trailer's required capacity.
