A weight-distribution (WD) trailer hitch instead of a weight-carrying (WC) trailer hitch.

A WD hitch moves some of the tongue weight (TW) off the rear axle of the tow vehicle to the front axle, and it moves some of the TW off the rear axle to the trailer axles. Here's a link to a WD hitch components. The shank goes into the receiver. The other parts go onto the trailer tongue.
Strait-Line Weight Distribution System w Sway Control - Trunnion Bar - 12,000 lbs GTW, 1,200 lbs TW Reese Weight Distribution RP66084

Because of the see-saw effect, an ordinary WC hitch removes some of the weight from the front axle and adds it to the rear axle. Not a good. Most 2" receiver hitches have a limit of 500 pounds max tongue weight when used with a WC shank and ball mount (WC hitch). Here is a link to a WC ball mount:
Curt Fusion Ball Mount for 2" Hitches - 2" Ball - 3-1/2" Drop - 7,500 lbs Curt Ball Mounts C45154

The rear step bumper of most pickups have provisions for adding a trailer ball. But that is a WC hitch and usually limited to 500 pounds or less TW.

The weight rating of a WD hitch is for the heaviest tongue weight (TW) you might ever have on that trailer. To determine the minimum TW rating of any WD hitch you might need, use 15% of the GVWR of the tandem-axle trailer you might tow with that hitch.

That assumes you will not overload the trailer. TW runs from about 12% to 15% of gross trailer weight for most tandem-axle trailers. So if you use 15% of gross trailer weight to determine your max TW, then buy a hitch with not less TW rating than your max TW, you should not have any problems with overloading the hitch.

Most quality WD hitches are available with TW ratings of 800, 1,000, 1,200, 1.400 and 1,500 pounds, and some go as high as 1,700 pounds TW for really-heavy "bumper-pull" trailers with GVWR over 12,000 pounds. And a few go as low as 600 pounds TW for itty bitty trailers that the owner wants the assurance of minimum trailer sway.

For example, if your tandem-axle trailer has GVWR of 7,500 pounds, then you need a WD hitch rated for a minimum of 1,125 pounds TW. So for that example a WD hitch rated for 1,000 pounds TW would not be heavy duty enough, so you'd buy a WD hitch rated for more than 1,125 pounds TW. For most WD hitch brands, that would be a WD hitch rated for 1,200 pounds TW.

Another example: If your tandem-axle trailer has GVWR of 6,500 pounds, then you need a WD hitch rated for a minimum of 975 pounds TW. So for that trailer you'd buy a WD hitch rated for 1,000 pounds TW.
