Hey Geno, thanks for reaching out!
Your Alliance Paradigm 310RL lines up with a Lippert Rhino pin box so that's the set we need to look at. According to my research your Alliance Paradigm 310RL has a 15,000 GVWR so the correct MORryde Cushioned 5th Wheel Pin Box you need is the part # MR83QR rated for 14K to 18K Trailers.
What 5th wheel hitch are you using for this?
