When you have too many passengers or too much personal stuff, but not enough car, add a cargo carrier to the top or behind your vehicle using the trailer hitch of your vehicle to reduce in-cab crowding. We sell Thule racks and cargo boxes. For the cartop carriers, you'll first need cross bars - we sell those too! If your "cargo" is a kayak or canoe, check out our line of watercraft carriers to go on top of your vehicle.
