We just purchased a Bighorn 3685Rl and don't know how to transport our bikes This is our first 5th wheel and we have always had a bumper to attach a bike rack to. We have a ladder but we are hesitant to put bikes on it as we worry it will damage body or window and also take a toll on ladder. There is a large hook inside the front storage compartment and we are wondering if anyone knows what that is intended for and if anyone has attempted to use that area to transport bikes?
