Decision Guidance

This 18x31x12 carport is a good choice for customers seeking covered storage for RVs, boats, trailers, and larger vehicles while maintaining easy access through wide frame-out openings.

You may want to consider a larger building if:

• You need enclosed storage
• You plan to store multiple large vehicles
• Additional workspace is required

This size works well for customers looking for substantial covered protection without the need for enclosed walls or garage doors.
