Outdoor parking: cheapest, least protection
An open space on gravel or pavement solves one problem — the rig is off your driveway and off the street. It does nothing about UV, hail, snow load or freeze-thaw cycles.
In eastern Iowa that matters more than in a mild climate. Davenport gets hard freezes from December through February, real hail risk in spring, and enough summer sun to chalk gelcoat and crack vinyl in two seasons. Outdoor makes sense for utility trailers, work equipment and older boats where cosmetics are not the point.
