Recommendations for outdoor storage shed

I will also say that I have a cheap about 24"x48", plastic/resin "lean-to" type shed on the side of the house with a 5.9 Magnum on an engine stand in it.

It actually fits perfectly. I had to remove the plastic floor and rig a way for the doors to close since the hinge pin of the door rests in a hole in the floor.

It's done well for over a decade, but it's partially under the eave of the house and has a line of trees about 15 feet from it, partially providing a wind and rain break, and a screen from direct sun.
