What are the typical dimensions for RV storage spaces and how to measure my RV?

Finding the right storage space for your RV, motorhome, or travel trailer starts with one crucial step: knowing its exact dimensions. A space that is too small can lead to frustrating access issues or even damage, while one that is too large means you are paying for unused square footage. This guide will walk you through standard storage facility space sizes and the correct way to measure your rig to ensure a perfect fit.

Standard RV Storage Space Dimensions

Storage facilities typically categorize spaces by length, width, and sometimes by the type of coverage offered (e.g., uncovered outdoor, covered, or indoor). While dimensions can vary, industry standards provide a reliable framework for your search. According to the Self Storage Association, RV storage is a significant and growing segment of the industry, with facilities designing spaces to accommodate common vehicle sizes.

By Space Type

• Standard Outdoor (Uncovered): These are the most common and economical options. Typical widths range from 12 to 15 feet, allowing for safe door clearance and some maneuvering room. Lengths are usually offered in increments of 10 feet, such as 20', 30', 40', and up to 50' or more for large Class A motorhomes with trailers.
• Covered RV Storage: These spaces feature a roof and often three walls, providing protection from sun and rain. They maintain similar width standards (12-15 feet) but may have height restrictions, commonly between 12 and 14 feet, to accommodate most RVs.
• Fully Enclosed / Indoor Storage: This premium option offers the most protection. Spaces are similar in footprint to covered storage but are fully enclosed within a building. Height clearance is critical here and is often limited to 13 or 14 feet. Door widths are also a key factor, typically being 14 to 16 feet wide.

By RV Class

• Class B (Camper Vans) & Small Trailers: Often fit in spaces as short as 20 feet. A standard 12-foot wide space is almost always sufficient.
• Class C & Smaller Class A Motorhomes: Generally require a 30-foot to 40-foot long space. Width remains standard.
• Large Class A Motorhomes & Fifth Wheels: Frequently need the longest spaces, from 40 feet to 50 feet or more. Extra height for satellite dishes or air conditioners must be considered for covered or indoor spaces.
• Travel Trailers & Toy Haulers: Length is determined by the trailer itself, not a tow vehicle. Always measure the trailer from coupler to bumper. Many facilities require the tow vehicle to be stored separately.

How to Accurately Measure Your RV

Do not rely on the model's listed length from the manufacturer's brochure, as this often does not include added accessories. For a storage-ready measurement, follow this process:

1. Gather Tools: Use a long tape measure, a notepad, and a helper.
2. Measure Length: Start at the very front-most point (e.g., trailer coupler, motorhome bumper, or ladder). Extend the tape measure in a straight line along the centerline of the RV to the very rear-most point (spare tire, bike rack, or rear ladder). Round up to the next foot.
3. Measure Width: Measure at the widest point, which is often the mirrors or slide-outs. Critical: Always measure with mirrors extended and any slide-outs fully retracted, as they must be in for storage. Add at least 2 feet to this number for minimal door and maneuvering clearance.
4. Measure Height: Measure from the ground to the highest permanent point, which is usually an air conditioner unit, satellite dish, or roof vent. For travel trailers, ensure you measure when the trailer is level. Add at least 12 inches to this measurement for safe clearance, especially for covered or indoor storage.

Key Considerations Beyond Dimensions

Finding a space that fits is more than just matching numbers. Consider these factors before signing a lease:

• Maneuvering Room: Is there enough space in the aisle to back in or pull forward easily? Ask about the driveway width.
• Access Hours: Ensure the facility's gate access hours align with your needs for retrieval.
• HOA & Local Regulations: If you are considering home storage, thoroughly check homeowners' association covenants and local municipal codes regarding parking RVs on property. Many prohibit it.
• Facility Rules: Confirm policies on slide-out usage, washing, maintenance, and battery disconnect requirements while in storage.
• Insurance: Notify your RV insurance provider of your storage location. Some policies have specific requirements for long-term storage, and the facility may require proof of insurance.

By taking precise measurements and understanding standard storage space offerings, you can confidently select a secure and suitable home for your RV. Always verify the exact dimensions and rules with your chosen storage facility, as their specific layouts and lease terms are the final authority. This preparation ensures your investment is protected and ready for your next adventure.
