Just bought my first Ranger! Love it, but have a few questions. It is a 1997 488VS Camanche with tamdem axle trailer. When towing with factory cover, I have trouble keeping it from lifting off. I notice there is hidden grommets down both sides. Are there straps I should be using to tie it to the trailer? The previous owner told me to turn off the electrical breaker reset when boat is not in use. Will the automatic bilge pump still work if I do this? I leave it at my dock covered and should not take on water, but you never know.
