I really can't understand why anyone would wish to leave their equipment out under ANY circumstances no matter how well protected, except in an observatory setting and maybe not then.
Sheer idleness is maybe one reason and I would like to suffer from it, but I resist.
Manufacturers give us guide lines on storage, particularly of electronic components and if lucky will tell us what humidity and max and min temperatures to abide by.
I would not expect my computer to enjoy a life out on my balcony no matter how well protected and then bring it inside and hope it will perform well, in the winter at any rate!
For mechanical items it's not so severe. The worst we might experience is some rust or corrosion but you will still have to deal with it!
Electronic boards are a different matter.
We have no idea how well the boards in our mounts have been treated with conformal coating (if at all!) against moisture.
Just the same; why risk it?
Maybe it's OK if your climate, Tommax (Benny Hill) is fairly benign but I guess WI is pretty harsh.
Upstate NY is equally tough for me on for the occasions that the weather allows me to get out in the winter (very few). I am very happy to tote out my equipment from a warm dry apartment knowing that the elements have not been a worry to my equipment.
I don't really "wish" to, but I don't really have enough room to bring it in, though I suppose I could figure something out. However, it still takes time to set it up and break it down, but the bigger advantage to leaving it out is that once I get it aligned, it mostly stays aligned and equilibrated, and I don't have to do it again. If I had a garage where I could keep it set up on a cart and just wheel it out when I wanted to use it, I would probably take that compromise, but given the choice between setting up and breaking my rig down every time I want to use it, and leaving it set up and aligned all the time, I'll leave it set up.
