Are you using a Revolution pin box?
The reason I was asking is I just bought a 5er and looking to purchase a hitch
I have a F350 short bed so I would be utilizing the Reese Revolution that comes with the trailer
I have been reading that the companion is not compatible when using the Revolution unlocked
