Had mine for less than a year, towing a Jeep Wrangler, tows really well. Brakes are very smooth.
Been through the BC Rockies, no issue with the Jeep braking going downhill under engine braking, the Jeep will brake initially, but then just follows along unless I brake the motorhome again.
Download the installation manual, you do need to drill two small holes. Get the breakaway brake kit as well while you're at it.
