I don't like towing with a trailer. I have an open trailer(budgetary constraints). I've looked at all the permutations and a truck with a trailer is the only solution other than flat towing(remember those MW free towing hubs, I love them). Maintenance on a box truck as a hauler is much more expensive. The gas and insurance and the local or state police looking for $omething($). They are easier to park and they are easier on the road since you don't have that trailer behind you and idiots all around you. And of course it is a dedicated vehicle. You can unhook a trailer and then pick up a washer or parts or whatever.
