I got lucky and purchased a garage from my township, about 3 miles from my home. They kept road equipment in it but sold it because it "rained" inside in the winter. They heated it with unvented gas space heaters that caused condensation. I replaced them with vented furnaces and it stopped raining inside. Plenty of room for my 'C' and toad.
Features - 60' x 60' building and 40' high. Concrete floor with drains. Plenty of electric power, including a 30amp outlet for the RV, All metal and insulated, including roof. 3 12' x 12' doors with electric openers. 8' ventilation fan high on one wall and vent panel on opposite wall. Full bath including shower and work sink.
Because I'm unmarried and retired, I've added a 10' long bar and back bar, big screen TV with Dish Network, a juke box that plays 45's, a pin ball machine, a bowling machine, theater size popcorn machine, kitchen with fridge, freezer, stove, microwave. And no neighbors. I'm growing old, but I'm never growing up. :)
