So if I want to change something like changing in to the dexter nev-r-adjust breaks on my 2015 27RL does anyone know the actual part number I need to order?
You'll need to know the axle rating on your 27RL and then order the brakes for that application. The axle rating should be marked on the label on the front left corner and should be verified with the label on the back of each axle tube. The brake assemblies are also different for left or right side of the camper.
