Question:
Sorry for the confusion Kyle S. but I have a 2018 Ram 2500 Crew Cab with a 3.73 axle and looking to purchase a fifth wheel toy hauler with a Dry Weight 11939lbs and GW of 16000lbs. Will my Rm 2500 handle this? Thanks!

If your 2018 Ram 2500 4WD with a 6.4L V8 engine, short bed and 3.73 axle ratio is a Crew Cab your fifth wheel towing capacity is 12,630 lbs and if it is a Mega Cab it has a fifth wheel towing capacity of 12,240 lbs.
This means that yes, you will be able to tow the fifth wheel trailer with a GVWR of nearly 12,000 lbs like you wanted.
To tow this trailer you are going to need a sliding hitch to accommodate a short bed, and the best option for a fifth wheel hitch for your '18 Ram 2500 is the Curt A16 # C16521 because it is reliable and very easy to use.
The A16 is reliable because of its interlocking dual jaw system, meaning you have a highly secure connection with your trailer's king pin. It is easy to use because it has a handy indicator system which will let you know if the jaws on the hitch are ready to couple, uncouple or tow. This color-coded system, which you can check out in the accompanying photo along with the jaws, makes the process of hooking up or disconnecting your trailer much simpler.
The Curt A16 has a fully articulating head which also eases the coupling process and built in zerk fittings so you can lube the hitch without issue. The A16 # C16521 has a 16,000 lb capacity which is enough for the trailer you are looking to tow, and comes with a lifetime warranty.
To install in your Ram 2500 I recommend the Curt Custom Fifth Wheel Installation Kit for Ram Truck # C16427-204 because it was designed specifically for you truck and will not require any drilling into your frame, which is good for your truck and also makes the install process easier.
Finally, for a wiring harness that goes to your truck bed to power your trailer's lights you can use the Curt 5th Wheel/Gooseneck Custom Wiring Harness # C56000.
