You will want to go to the Replacement Hardware Kit for Trailer Hitches item # RHK. You will enter Draw-Tite and then 75882 to get the hardware required to install that hitch. view full answer...
The Rear View Safety Backup Camera # RVS-Tailgate looks to be the best replacement for the RVS-918 camera you have on your 2017 Ram ProMaster. Your camera is no longer available from Rear View Safety. The camera I have linked above has the same 5 pin connector as your camera. It may even be able to be mounted to the same bracket with some slight modification. view full answer...
There is a replacement converter section for your WFCO 8955 with part # PD4655V, but it is not compatible with lithium batteries. If you wanted to only replace the converter section then you could install the Progressive Dynamics Inteli-Power RV Converter and Battery Charger - Lithium # PD9160ALV in the space your current converter sits in.
It wasn't designed to be mounted into your power center but I've seen it done on a few of the trailers I've worked on so I know it's a possibility.... view full answer...
