Overview
About the 18x45 Class A RV Garage
This 18x45 Class A steel RV garage gives you 810 sq. ft. of enclosed steel space for a Class A motorhome, camper, travel trailer, boat trailer, oversized vehicle, tools or RV gear.
The 18-foot width gives you room for parking and side clearance. The 45-foot length gives you deeper space for longer RVs, storage bins, outdoor gear, spare parts or travel supplies.
This garage has a 14-foot height, vertical roof, and one 12x14 roll-up garage door for easier RV access. The 14-foot door height is useful for motorhomes and campers, but you should still measure your RV from the ground to the highest roof point, including AC units, vents, antennas, ladders and solar panels.
It uses a 14-gauge steel frame and 29-gauge metal panels. The vertical roof helps rain, snow, leaves and debris move off the building better, which matters on a 45-foot-long RV garage.
Every building is custom made. You can change the height, door size, colors, walk-in doors, windows, insulation, anchors, panel layout and certified wind or snow options based on your RV size, property and local code needs.
Delivery and professional installation are included. Call Garage Buildings to get your 18x45 Class A RV garage quote.

- 14-gauge frameGalvanized steel; 12-gauge upgrade available.
