MOAB, UT is 1783 miles from my house, 27 hours straight thru, so it's do-able with a team. At 15 miles per gallon, and $4 a gallon, thats $476 each way for 6 guys, or $160 round trip fuel each, plus the MINI van rental for a week with unlimited miles for $500 a week (don't tell them where we're going) or $85 each, so before food, hotel/camp, and jeep freight, $250 each this way.
I figure $1000 each at the best on the cheap. What a country!
