How to size it
Use the loaded trailer. A public scale is the check NHTSA points to, because dry weight leaves cargo, water, and gear off the number (NHTSA towing safety).
Ten percent of 5,000 lb is 500 lb. Fifteen percent of 5,000 lb is 750 lb (CURT tongue weight). Under 500 lb the trailer may sway. Over 750 lb the tow vehicle is less responsive, especially turning and braking.
Class 3's weight-carrying tongue limit is 800 lb, and 750 lb is under 800 lb (CURT hitch classes). Gross weight of 5,000 lb is under the 8,000 lb Class 3 cap. Class 3 is the most common class on full-size pickups and SUVs. The receiver is 2 in. You can still use a weight-distribution hitch — the chart allows up to 12,000 lb and 1,200 lb of tongue with one — but the 500 to 750 lb band does not force that column.
Match the coupler first. The 2 in ball row is 3,500 to 12,000 lb, which contains 5,000 lb (CURT hitch balls). The 2-5/16 in row starts at 6,000 lb, so it is the next size up, not this trailer's chart row, unless the coupler is stamped 2-5/16 in. The ball rating is gross weight and must exceed 5,000 lb. Part numbers vary.

Plan on trailer brakes. Many states require a separate braking system and a breakaway switch when loaded weight is more than 1,500 lb (NHTSA towing safety). Electronically controlled brakes need a controller in the cab and the wiring to run it. Surge brakes are a separate hydraulic system at the hitch and are not legal in every jurisdiction; check your state's motor vehicle administration.
Class 3 on a full-size truck still cannot outvote the owner's manual. Check GVWR, maximum trailer weight, maximum tongue weight, GCWR, and GAWR, and fit a hitch to those specifications (NHTSA towing safety). Capacity stops at the lowest-rated component, and no hitch increases the vehicle's maximum (CURT hitch classes). The longer version of that limit is towing capacity explained. The trailer tow calculator compares the sticker values you type in.
A 500 lb tongue is over 300 lb, so do not set a bathroom scale under the coupler and read it directly. A tongue weight scale under the jack is the straightforward method CURT lists (CURT tongue weight).

FAQ
Is Class 3 the right hitch for 5,000 lb?
Yes for the published class chart. Class 3 is rated up to 8,000 lb gross and up to 800 lb of tongue weight on a 2 in receiver (https://www.curtmfg.com/types-trailer-hitches). Five thousand pounds is under 8,000 lb.
Does the tongue weight fit without weight distribution?
Ten percent of 5,000 lb is 500 lb and 15 percent is 750 lb (https://www.curtmfg.com/trailer-parts/couplers/learn-more). Both are under the Class 3 tongue limit of 800 lb (https://www.curtmfg.com/types-trailer-hitches). The weight-distribution column (12,000 lb and 1,200 lb) is headroom, not a requirement for this band.
What ball size is listed for 5,000 lb?
A 2 in ball is listed from 3,500 to 12,000 lb (https://www.curtmfg.com/towing-accessories/trailer-balls/learn-more). A 2-5/16 in ball is listed from 6,000 lb, so 5,000 lb is below that row. Match the coupler first, and pick a ball whose gross rating exceeds 5,000 lb.
Do I need a brake controller?
Many states require a separate braking system and a breakaway switch above 1,500 lb loaded (https://dmna.ny.gov/nynm/training/NHTSA_TowingSafety.pdf). Five thousand pounds is over 1,500 lb. Electronically controlled brakes need an in-cab controller and wiring.
