Washington state requires all vehicles towing a trailer over 3000 pounds to have an electric brake controller. This is a requirement for all our travel trailers except the tent trailers. If you do not have one, you can have Truline RV install one or a service provider of your choice. You must have an electric brake controller installed prior to your pick-up. There will be no refund of money on departure day if you do not have the electric brake controller.
