The sizing of this shelter falls into CanvasMart's intermediate-to-large-sized shelter range. For those who need a larger structure, we have the upgraded extra large RV/Bus shelter at 20' wide x 32' long x 16' high. This model comes with an 11' wide x 12' high roll-up door and a walk-in door at the rear of the building. Constructed with the included pre-cut 2" x 6" wood frame and 6oz silver/black poly covering, this unit is sure to satisfy large storage needs and your budget.
