Best storage solution I've seen are shipping containers. Ypu can get a short or long one. Nice floor, weather proof, wide doors to get in and out. They're over $1000 but you get a huge amount of storage and only need a level site.
Thanks so much for that info. I'm a gear head but have never gotten in to any of the body work due to time, space and equipment restraints. I learn something g new every day.
