By the look of the pink mazda miata and old RV you are a car person, so you must have couple of old seat belts laying around, use a seat belt or two and rig it.
That's why I like to have them hanging.. I moved my mill on rollers, didn't like it much but no catastrophe. Glad you're ok.They are top heavy. I was rolling my new to me K O Lee 6X18 into my shop by myself "you big dummy"on pipes and boards and turned it over on top of me. I'm OK but it busted the motor mount and motor. Got it back up and running but it could have been worse.
