Gooseneck adapter on Montana 5er with MOR/Ryde hitch pin box

Hi all,
I am in the process of purchasing a new Montana 3440 RL 5er to replace my old Keystone cougar.
My truck has a factory (Ram) Gooseneck ball instead of the 5th wheel hitch, and I have the Anderson mfg gooseneck adapter on my Cougar - just curious if anyone has any experience with a gooseneck adapter on a Montana with the MOR Ryde hitch pin ( good or bad)
