You'll need a button down or velcro style mooring cover. That Conneaut boat cover, Amish family seems to be a huge favorite on the site. Custom fit, so you aren't getting water in your boat.
Make sure your hull is water tight. I don't trust mine, aluminum rivet construction. It usually doesn't have any water in it, when I moor it for 4-5 days, but not sure if that would be the same for all of the time. You can get an automatic bilge pump with a float, and run a solar panel to trickle charge your battery. If not, then you'll likely want to pull your batteries after every use, and probably your depth finder and anything else that is easily removed and worth anything. People are idiots, so you need to account for that.
I personally just keep my boat close to the lake in storage. So, I end up doing about the same pulling of certain things that go home with me in my truck and need to remember on every trip as if I moored. It's a lot cheaper than mooring, but takes 15 minutes before and after every trip. Mooring is still going to take 5 minutes or so. It saves wear and tear on my vehicle, and space on my driveway/garage, which is why I really do it. I don't have a custom fit cover or auto bilge. So if mooring for a few days, and it rains hard, it's in there until I bilge it out.
It would be nice to just get there and go. If it makes sense, then it would be great. I can't justify the additional cost, of getting a boat that I would trust and mooring cost.
