3 tow vehicle choices for single long haul tow-need help

Hey guys (and girls?), thanks for all the great advice. I've looked over everybody's suggestions and talked it over with my sister, and it's been decided that we are going to try out the Ford Flex. We've got a WDH for it, and hopefully it should make the journey trouble free. I'll post back with details after the trip on how it towed. Thanks again for all the info.
