I have a National 2000 seaview 31 ft.and at a recent inspection was told I should thinks about new brakes rotors and pads. The vehicle weighs 17000lbs and I have towed a dinghy (2800lbs) about a third...
Great idea my calipers rotors and pads were done at 40k on a f53 chassis, the rotors were pitted and salt had got to them from good old Florida air, I always believe braking the most important part of the ride, check around for prices seem to be some shops fairly reasonable good luck
