The majority of auto carriers (open and enclosed transporters) transport vehicles on two levels or decks. By paying the additional cost to have your vehicle positioned on the top level, you eliminate the potential of fluids leaking from other vehicles onto your car or truck. We highly recommend owners of convertibles to purchase this option. Our top load guaranteed option is $100. You also have the option of requested/preferred top load, which is free but does not guarantee a top load. Driver will be instructed to place your vehicle on the top deck if possible with requested/preferred top load.
