If three 18 gallon tubs is the extent of your possessions to move from MA to OK, why not just box the stuff up and haul it over to UPS and ship it to yourself to be held for pickup at the UPS office in the city you are moving to. They will hold it till you arrive. That way you take only the bare minimum of items you need for your trip (plus dog) from MA to OK, and the rest gets safely hauled there by the guys in brown trucks. I have known lots of people who have self moved from A to Z by shipping most of their stuff in small to medium sized boxes via UPS. The U pack ABF containers or PODS are mainly for people who have a lot more household stuff than you have described.
