I have just purchased a camper trailer with a tare weight of 880kg and a GVM of 1500kg. It has 10inch electric brakes but I am yet to have the contoller fitted. It has a standard Subaru tow bar and ball mount. Could anyone suggest what I may need to do to improve my towing such as heavy duty shocks or adjustable ball mount? Is a weight distribution hitch necessary? Thanks. I am a newby and would very much appreciate any advice.
