Mike, you says the seller cannot help you, and your wife is physically light, but a good worker.
Also you will be loading this machine in a driveway, so it's probably sloped.
Things can go wrong very quickly in this situation. I've seen it happen.
I would absolutely take the jointer apart - remove the fence, stow it on the bed of your truck, then the tables and stow.
Now you just have the base and the motor to move.
These are simple machines and it will not be difficult to put it back together, and you'll save yourself a potential disaster. Plus you won't need to haul a trailer for the trip.
