Yes
We estimate a loaded Sun Tracker Party Barge 20 DLX on its trailer at about 4,210 lb. 6 of 6 1500 engine/package options pass with a 20% margin (for example the 3.6L Pentastar eTorque V6, 3.21 axle).
Check your exact setup (add your door-sticker payload and real trailer weight)
Sun Tracker Party Barge 20 DLX loaded towing weight
| Published average package (boat + motor + trailer), Sun Tracker | 3,745 lb |
| Fuel: 32.1 gal x 6.1 lb | 196 lb |
| Gear allowance: 10% of boat + 115 HP engine + fuel | 266 lb |

We also computed boat (2,080 lb) + heaviest 115 HP-class engine (386 lb) + estimated trailer (900 lb) and kept whichever total was higher.

"Published rating" is the lowest–highest conventional (ball-hitch) rating Ram prints for that engine/package across cab, bed, drive and axle choices. PASS means the loaded trailer is at or under 80% of the lowest rating. Ram: ratings include 300 lb of passengers; trailer weight and payload ratings are mutually exclusive; weight distribution recommended over 5,000 lb; Class IV receiver tongue limit 1,100 lb.
Tongue weight vs payload
Tongue weight should be 10–15% of the loaded trailer: about 421–632 lb. That comes out of your truck's payload along with everyone in the cab, so with two adults (300 lb) you need roughly 721–932 lb of payload before any cargo in the bed.

Confirm with your door-jamb sticker and owner's manual. Your exact truck's rating depends on cab, bed, drive, axle ratio, options and tires, and your boat's real weight depends on its engine, options, fuel and gear. When in doubt, weigh the rig at a CAT scale.
Gear you may need
Placeholder links (not affiliate links yet). Disclosure.
Trailer brake controller
Boat trailers over about 3,000 lb usually need working trailer brakes (check your state's law); an electric-over-hydraulic or electric setup needs a controller in the truck.
Class IV receiver hitch & ball mount
Match the ball mount drop to your trailer so the boat rides level; the hitch rating must cover the full loaded trailer.
Tongue weight scale
The only way to know your real tongue weight (10-15% of the loaded trailer) before it eats your payload.
