Unless the sag you're experiencing is extremely minor, a weight distribution system wouldn't be a waste of money. When the rear suspension of your vehicle is compressed, many things happen. Your headlights aren't aimed correctly any more, the handling of the vehicle is negatively affected and the braking performance is reduced because the front vehicle brakes so the majority of the braking. Adding a w/d system would indeed provide a safety upgrade.

Any time the fully loaded weight of the trailer is greater than half the vehicle weight, using weight distribution is recommended. To choose a weight distribution system, you'll need to first determine the fully loaded and ready to tow tongue weight of your trailer. To that figure, add the weight of any gear stowed in the truck bed behind the rear axle. I've linked to an FAQ article that explains how to do this. These combined figures make up the Total Tongue Weight (TTW) of your set-up. The TTW of your trailer should fall as close as possible to the middle of the effective range of the weight distribution system you choose.

A trailer's tongue weight is generally 10-15 percent of its gross weight. Given the 5-6K weight you mentioned, your tongue weight could range between 500 and 900 lbs.

A 5-6K trailer is still pretty heavy, and could easily be swayed by crosswinds or turbulence caused by passing traffic. For a more severe sway condition, the Reese Steadi-Flex system would be an excellent choice. The system combines proven weight distribution with highly effective sway control. If the fully loaded tongue weight of the trailer is between 600-1200 lbs, the Reese SC # RP66560 is what I'd recommend. If your tongue weight is at the lower end of the spectrum, use the # RP66559, which is effective on tongue weights between 500-1000 lbs. Both kits include the weight distribution shank, but the properly sized trailer ball is sold separately as part # 63845 for a 2 inch or # 19286 for a 2-5/16 inch ball.

For minor sway, Pro Series offers some reasonably priced options. For tongue weights below 750 lbs, use the # PS49582 or for tongue weights from 750-1000 lbs, use the # PS49583. Both systems can use a friction sway control like # 83660 to help minimize trailer sway. If your trailer is longer than 26 feet, a second sway control unit, part # 83660 is recommended. All three of these systems include the shank and the 2-5/16 inch trailer ball.
