Maybe you should look into transporting something heavy for someone that will help pay for the fuel? For example, I had a big heavy electric motor hauled to LA by someone, who was moving a few things down on the trip in a van.
Can check craigslist, but there is also some specific hauling website.
I have done this quite a bit. Need to be careful though because then you are a commercial vehicle in the eyes of the law. Doing a friend a favor for some gas money is one thing. I would also say as a first trip I would not want to be responsible for timely delivery of someone else's goods.
