I want to go on an unusual roadtrip. I have sailed here to New York from Europe, and I'd like to take my boat overland to Berkeley. I have a trailer down in Georgia I can use (I'll pick that up with a friends car and bring it to NY), however I need a one-way rental with unlimited miles which could tow my 6500lbs boat across to California. I think something like an E350 Econovan, or a Ford F250.
Has anyone seen such a vehicle that is affordable, which I can drive one-way?
