Hi Logan!
Your 2021 Dutchmen Astoria 2943BHF uses the 1621 pin box (I confirmed this directly with Lippert with the sticker info you provided), so the Curt Helux Shock-Absorbing 5th Wheel Pin Box - Lippert Rhino - 24K GTW - 6,000 lbs TW # C83RJ will not be the correct option for you. With that 1621 pin box, I recommend the following option:
Curt Flex Air 5th Wheel Pin Box - Lippert 1621 - 18,000 lbs # LC328492
Not only will this fit your camper perfectly, but it will also match your weight capacities a lot better. From what I could find, your Astoria 2943BHF has a gross vehicle weight rating (GVWR) of 12,000 pounds. The Flex Air has an 18K capacity and the Helux has a 24K capacity, so the Flex Air will be the better option for you. At least for now.
Curt will likely have a Helux option that will fit the 1621 pin box in the future as that is one of the most common pin boxes on the market, I just don't know when that will happen.
What truck are you towing your Dutchmen with?
