Definition and Purpose

An RV garage is designed to accommodate RVs, campers, or motorhomes. It is a place where you can safely and securely park your vehicle, providing it protects against harsh weather conditions, theft, and damage.

The primary purpose of an RV garage is to provide a designated space that is custom-built to fit your RV’s dimensions, ensuring that your vehicle is protected.

RV garages come in many different sizes and styles.

The size required for your RV garage depends on the size of your RV. A standard RV garage is typically 14 feet in height and 12-16 feet in width, with a length of about 35 feet.

You can also customize the dimensions to the size of your RV by adding extra height or width to provide additional space.

Why Do You Need an RV Garage?

RV Storage

The primary purpose of an RV garage is to provide safe and secure storage for your RV when not in use.

It protects your vehicle from harsh weather conditions like hail, rain, or snow. It also keeps your RV safe from theft or vandalism while away.

Moreover, RV garages offer you peace of mind, knowing that your vehicle is in a safe and secure place.

Protection from Elements

An RV garage protects your vehicle from harsh weather conditions like wind, snow, and hail. It can help reduce any wear and tear caused by exposure to the elements and potentially cause expensive damage.

It can also help reduce the cost of maintenance and repairs in the long run by reducing exposure to natural ingredients.


Having an RV garage provides the convenience of preparing your RV for travel without leaving the comfort of your home.

This saves you from time-consuming tasks like packing and other necessary arrangements that would be more difficult to perform off-site.

Moreover, maintaining an RV garage reduces the need to store RV equipment inside your home or occupy outdoor spaces, freeing up space in and around your home.

Popular RV Sizes

The most popular RV sizes include travel trailers, fifth wheels, pop-up campers, and motorhomes.

The standard sizes for these RVs range from 10 feet to 35 feet in length.

Therefore, it is essential to measure the size of your RV and add an extra 2-3 feet to the width and height to ensure that it will fit comfortably in the garage.

Class A, B, and C Motorhome Sizes

Class A, B, and C motorhomes have different size requirements.

Class A motorhomes are the largest and require a minimum clearance height of 14 feet. Class C motorhomes are smaller and require a clearance height of 12-13 feet.

Garage Door Styles

There are two main styles of garage doors, roll-up and sliding.

A roll-up garage door works by rolling up like a curtain while a sliding garage door slides to the side. Both styles of garage doors can be tailored to fit your RV garage’s dimensions.
