I am looking for a good bike rack that holds four bikes so we can take all our bikes with us when we go to the Cape. I have heard that the Hollywood Racks F4 Heavy Duty 4-Bike Trunk Mount Rack is pretty good, but I am wondering whether or not we would still be able to use the trunk with this sort of rack, or whether the way it is mounted would prevent this. I am not really clear exactly how the mounting works. We want to be able to use the trunk since we will have bags to bring with us.
