We had other yard tools (log splitter, chipper, HF trailer, etc.) that deserved better storage than outside under tarps, and had to be moved out of our basement/garage if I was going to have a proper wood shop, so we bought a 3 bay metal shed. Out here, there are plenty, and plenty of places places that sell them. Not sure how practical this would be in your neck of the woods John.
Since we live on the side of a hill, we had to buy an adjacent piece of land that had a flat place near the road. We then discovered we couldn't simply build a garage, as the county requires a livable space on a lot. Rather than build a better building with septic system, water, electricity, and cooking facilities, we had our lots combined into one, which took time and a survey. Then we worked with the metal building people to get it permitted. I cut down trees where we wanted it built and hired a dirt guy to prep the pad, pull permits for that, and pour the concrete. Then the metal building factory shut down due to Covid. Took several years from buying the land to getting the building ready for the teardrop and other equipment, but we felt it was worth it. An awful lot of effort though!

The building stops all the weather pretty well, but not the rodents, which are a perpetual battle out here. Oh, and I'm part pack rat myself and this offers more evil tempations for storing my booty.
