Need ideas for moving from Idaho to Vermont?

Ok so we have a 2004 Kia Optima FWD that we either must drive or haul with us from the great state of Idaho to the other great state of Vermont. Also taking with us, a queen size bed (no headboard just frame) a couple of small dressers (3 and 2 drawer) a medium sized entertainment center and large box TV, small curio cabinet, 2 gliding rocker chairs w/ stools, plastic chairs, plants, kitchen appliances and dishes, clothing, etc. So all of these items could easily fit into a small apartment right? Ok so that gives you an idea of the size of truck we'd need to rent. UHaul is asking about $1200 plus another $200 for a tow dolly for the Kia. Penske is a bit lower but apparently get worse gas mileage. I also have four cats. I'm already getting rid of my couches, coffee table, washer/dryer, etc. There has got to be some way to do this. We though of trading in my car for a truck which could haul a small uhaul behind it and that would be ALOT cheaper than driving a larger UHaul across country. Please help, sincerely, John & Danielle
