If you own a truck and/or trailer you can now make money moving other people's items for them with a service called Uship.com. It's like eBay for shipping, you simply play UPS's role.
My cousin uses the service to pay for his gas to destinations he wants to go.
Heck, there's even a T.V. show about it called "Shipping Wars".
