This will take some calls and will depend on how attached you are to stuff.
Overall, if I had a 1200 square foot house totally furnished and wanted to keep it all I would hire someone to move it all. I would make sure they knew about the safe and could handle it and pay for it all.
Since I am a single cheap bum I move stuff myself. I moved my sister who had way too much stuff from illinois to ohio. I drove up and moved her using a u-haul with a car trailer, my car on the trailer. She drove her car. Then I eventually drove home.
I also moved myself a couple summers ago, this included car engines and all sorts of big stuff like engine hoists and compressors. Take your time, use your head, and know what you can not do. I was able to cheat using the engine hoist to load stuff and then I dismantled it so it was last on and first off.
Good luck, and if you land in lower ohio and buy beer after wards I will help unload some of the stuff. So as someone mentioned, let others know what you plan and know to ask for help.
