The lube plate you mentioned is a 12 inch lube plate, and B&W recommends a 10 inch lube plate for the Patriot, so I recommend the following:
- Lube Plate for Reese 5th Wheel Trailer Hitches - 10" Diameter # RP83002
The # RP83002 will indeed stay on the king pin without any other accessories or parts. view full answer...
Yes, the Ultra-Fab 5th Wheel King Pin Tripod Stabilizer - Steel - 37" to 50" - 5,000 lbs # UF19-950001 will work as long as your pin box height is within 37 to 50 inches and the pin weight is less than 5000 pounds. view full answer...
