I need to remove a rear brake valve, so I obviously need to safely support the rear of the coach to release air and then go under it. I don't know exactly what to call them, but I'm calling them the drag guards at the rear bumper that keep the back end of the coach from dragging... if those are blocked, will they safely hold the body of the coach up?
If not, feel free to link me to another post about how to do this. I'm sure it's discussed I was just having trouble finding the relevant posts.
Thank you,
