POP is correct. i'm a sucker, and i helped my sister move from texas to portland. the largest u-haul (POS) fit all of her belongings. her fiance and her took the dogs and a brand new truck on a roadtrip, vacation..camping along the way. in the meantime, my brother and i, drove all of her stuff in that POS truck, with a tow dolly pulling her rover discovery all the way to portland. it was hell. she did make the mistake of giving us her credit card, and authorizing us to use it. we charged everything!
we spent wayy less than $15k. i bet her move cost $3k.
i say unload everything you dont love. sell it, give it away. rent a big truck for the rest and road trip it.
funny story. on that move. this alarm clock...it is a chicken with a guitar. it went off in the back of the truck. it sang, "get up, get up, it's time to get up, you sleep head...cockacockadoo!" the entire length of california, until the batteries died. it was buried in the stuff..we listen to that for hours. i almost went mad.
