At RV Storage Depot that’s an 11×32 space.

Length: 28′ 10″overall
Width: —not published
Height: —not published

To scale: your rig in an 11×32 outdoor self parking space.

Outdoor self-park fits most trailers

Most travel trailers and smaller motorhomes do fine in a secured outdoor space. If roof seals and tires matter to you, ask about indoor valet.
