Welcome to the forum. I am no mechanic - by any stretch - but are there other implications than removing/disconnecting the shaft? Lubrication, charging, steering, etc? If it's a simple matter of disconnecting the shaft then I would think as a mechanic it would be an easy task to install a disconnect kit - I think Remco sells them. As others said, crawling under a car in even in optimum conditions (never mind dirt, mud, gravel, rain) every single time you hook and unhook the car will get old FAST. But, as others said, everything is a compensation. maybe you'd rather do the work than buy a new toad or a trailer. To each is own and I certainly respect someone who even knows how and is willing to do that.
On edit: If you are adamant about keeping your car, you may want to look into a trailer to tow your car. You could back it up, no drive shaft disconnect etc. Of course you have to have a place to store the trailer but everything is a concession. And rather than buy one, rent a trailer to see if that's an option that works. Also you may want to consider leaving the car at home and renting one at various destinations. We will do that on small trips. You can get deals as low as $25-35 a day.
