What Size Storage Unit Does Your RV Actually Need? A Boerne Owner's Guide

What size storage unit does your RV need? Class A Class C travel trailer sizing guide, Boerne, TX

The most common error RV owners in Boerne, Bulverde, and Fair Oaks Ranch make when reserving storage for the first time is booking a space based on the wrong measurement. They look up the length of their RV, find a facility that lists spaces in that range, and reserve — without accounting for the tow vehicle, the hitch overhang, or the turning clearance required actually to maneuver into and out of the space.

Understanding what size storage unit your RV actually needs starts with measuring the right things, not just the coach length listed in the owner's manual. This guide walks through the sizing requirements for every major RV type — Class A motorhomes, Class C motorhomes, travel trailers, and fifth wheels — and what to confirm with any storage facility before signing a lease.

The Number That Actually Matters — Total Stored Length

Storage space sizing is based on the total length of everything that will occupy the space when parked — not just the vehicle itself. For motorhomes, that means the coach length plus any tow vehicle hitched behind it. For travel trailers and fifth wheels, it means the trailer length plus the tow vehicle length when connected.

This distinction matters more than most first-time storage renters realize. A 35-foot Class A towing a small SUV occupies roughly 55 to 60 feet of total length. A 30-foot fifth wheel connected to a long-bed dually adds another 20 feet of truck in front of the kingpin. Booking a 35-foot space for either of those configurations creates a problem that becomes apparent only when the rig arrives and does not fit.

Class A Motorhomes — Sizing Requirements

Class A motorhomes are the largest and most variable RV type in terms of storage space requirements. Entry-level Class A coaches start around 25 feet. Mid-range models run 32 to 38 feet. Full-profile diesel pushers at the top of the market can reach 45 feet. Add a tow vehicle, and the total footprint exceeds 50 feet in larger configurations.

Here is what Class A owners need to confirm before reserving:

Total length including tow vehicle — measure from the front bumper of the coach to the rear bumper of any towed vehicle with the tow bar or dolly attached
Drive aisle width — a Class A requires significantly more turning clearance than a travel trailer; confirm the facility's aisles accommodate the turning radius of your specific coach
Overhang clearance — full-profile Class A coaches have rear overhangs that extend beyond the rear axle; spaces need to accommodate the full rear swing on a turn
Height clearance for enclosed units — Class A coaches with raised roof profiles or roof-mounted AC units need height confirmation for any enclosed storage option

Class C Motorhomes — Sizing Requirements

Class C motorhomes are built on a truck chassis with the cab-over sleeping area as the signature feature. Most Class C coaches run between 22 and 35 feet — a more manageable size range than Class A, but still requiring space confirmation rather than assumption. The most common Class C sizing error is failing to account for a towed vehicle behind the coach. A 28-foot Class C towing a small car adds roughly 14 to 16 feet, bringing the total stored length to 42 to 44 feet.

A storage space rated for 30 feet will not accommodate that configuration. Class C owners should also confirm turning clearance in the facility's drive aisles. The cab-over design creates a longer front overhang relative to the front axle than a standard vehicle, which affects how the coach tracks through turns.

Travel Trailers — Sizing Requirements

Standard Travel Trailers

Travel trailers cover the widest size range of any RV type — from compact 16-foot units suitable for a standard storage space to extended 38 to 40-foot models that require the same long-space configuration as a Class A. The trailer length alone does not determine the storage space needed. The tow vehicle must be factored in.

A 26-foot travel trailer connected to a full-size pickup truck occupies roughly 42 to 45 feet of total length when stored. A compact trailer behind a midsize SUV may fit in 30 to 32 feet. The combination of trailer and tow vehicle — measured from the front of the truck to the rear of the trailer — is the number to bring to the storage facility when reserving.

Fifth Wheels

Fifth wheels connect to a hitch mounted in the bed of a pickup truck, which means the front of the trailer overlaps significantly with the rear of the truck when connected. That overlap affects total stored length in both directions — the rear of the trailer extends well behind the truck's rear axle, and the front of the trailer sits over the truck bed.

Fifth wheel storage sizing requires measuring the full connected length from the truck's front bumper to the trailer's rear bumper — not the trailer length alone. A 35-foot fifth wheel connected to a long-bed dually typically occupies 52 to 56 feet of total space. Confirm this measurement with the facility before reserving.

What to Ask Any Storage Facility Before Signing

Beyond the length of the space, several facility characteristics affect whether a given space actually works for a specific RV configuration:

Maximum space length — confirm the facility has spaces rated for your total connected length, not just the coach or trailer length alone
Drive aisle width — adequate turning radius for the specific RV type matters as much as space length, particularly for Class A coaches and large fifth wheels
Paved versus unpaved surfaces — paved driveways provide consistent footing for large vehicle maneuvering; gravel and dirt lots create additional risk for wide, heavy RVs
Height clearance for covered and enclosed units — confirm clearance for any roof-mounted AC units, antennas, or raised roof profiles before reserving an enclosed unit
Pull-through versus back-in spaces — some owners prefer pull-through configurations for easier maneuvering; confirm availability if this matters for your rig
