What wall height makes the most sense for a 45×140 if I’m storing Class A motorhomes or tall trailers?
Choose a 16-foot eave height. That clears the 13′-6″ roofline of a Class A, leaves 2-3 feet for overhead door tracks, insulation, lights, and fire sprinklers, and lets you install 12′×14′ or 14′×14′ roll-up doors without hitting the rafters or haunches.
For a 45×140 RV storage row, an 16-foot eave height is the sweet spot. Here’s why.
1. Vehicle clearance: modern Class A coaches top out at 13′-6″. An 16′ wall gives roughly 2′ of free space, so door coils, roof insulation, sprinkler piping, and LED bays fit above the rig without you trimming AC shrouds.
2. Door size flexibility: With 16′ eaves you can spec standard 12′×14′ or 14′×14′ roll-up or sectional doors. That keeps hardware inside the jamb and avoids costly high-lift tracks.
3. Structural efficiency: Our galvanized/red framed, bolt-up steel building kit uses straight columns and comes with interior partition panels to divide the units into 14′-20′ x 45′ units.
