Purchased this unit in Nov last year and had brake issues. Camping World has been good working to fix the issue but Dexter Tow Assist is not working. When other vehicle is attached to the 5th wheel, brakes dont work. Hooked my truck to a Seismic 5th wheel with Tow Assist, worked fine. Its not working on my unit and I have NO BRAKES. Components have been replaced but Dexter ds not seem to be in any hurry to fix the problem. I have towed other 5th wheels without Tow Assist with no problem and again, the Seismic didnt have a problem with my brake controller.
