I'm moving from Philly to Winston-Salem--it's about an 8 hour drive. To the people paying $3000+ plus to move all their stuff: is that really even worth it? Why don't you just craigslist the hell out of furniture/TVs/etc when you get down there? And yes, craigslist is a verb.
BTW, I used a UHaul yesterday for some preliminary moving and got a charming 6 miles to the gallon. The guy said that was pretty standard.Huzzah.
