You learn a lot about your vehicle when driving long distances. Since September of 2004 I have driven my deuce in the states of Virginia, Tennessee, Kentucky, West Virginia, Maryland, North Carolina, South Carolina, Georgia and Florida for a total of about 11,000 km (6,600 miles).
I think I'm ready for something more of an adventure, perhaps Alaska.
I can only use cooking oil in the summer time. It starts roughly when the temp drops below 65F (15 C).
For a longer trip, I'd use the trailer, which can easily carry 40 5-gallon jugs of biodiesel/cooking oil in addition to the other supplies.
What kind of fuel milage do you get? Do you travel alone?
