One more question.
Just got a 25 foot RV 5th wheel tandem axle.
Do I need trailer brakes for my '05 2500 diesel in California?
Thanks
As far as what you "need" is dependent on the DOT laws for your state.
Are you asking if you need to install trailer brakes on your 5th wheel, because it probably already has them installed, or are you asking if you need to use them by hooking up a brake controller?
If your trailer has brakes, you need to hook them up using the brake controller. It is safest way to travel with your trailer.
