We do not have the ability to modify any of the RV hitches like Curt # 13703 that we sell and that includes something like addition of a second receiver opening to allow use of a hitch motorcycle carrier that requires dual receivers. At one time we used to offer a swivel-type wheeled motorcycle carrier that required multiple receivers in order to support the substantial combined weight of the carrier itself plus the loaded motorcycle.
I recommend you contact Coachmen RV with your 5th wheel's... view full answer...
