For many RV enthusiasts in colder climates, the fall months usher in the death knell of the camping season. Their rigs must be cleaned and winterized and stored until spring comes around again. Storing rigs during this time becomes a challenge. There are plenty of storage options out there, but how do you choose which one is right for you? Among the many options, there is one unique one that many people don’t know about. And that’s underground storage.

There are a few companies in the country that maintain expansive spaces in limestone caves and mines that accommodate subterranean storage. Here are just 5 benefits this option provides:

Low Humidity

Most underground storage facilities claim to maintain humidity levels anywhere from 52% to 65%. Because of these relatively dry levels, storing an RV underground can help prevent the growth of mold and mildew and keep other moisture damage at bay.

Climate Controlled

Like the benefit of low humidity, an underground storage facility that stays at a consistent temperature – whether naturally or because of air conditioning – means your rig won’t undergo extreme temperature changes as it might if stored outside or even in a covered facility. The ideal temperature inside an underground storage facility should be in the 50 to 65 degrees Fahrenheit range.


Underground storage facilities typically have security systems in places to help protect stored assets. Many have surveillance cameras and even employ guards to patrol the facility. Additionally, people are often escorted by an employee when parking their rigs, which means anyone entering the facility will be supervised, greatly reducing the chance for random break-ins and thefts.


Tired of scrubbing black streaks, dirt, and debris off your rig every year? When you use underground storage, you won’t have to clean your rig the same way you would after storing it outside or in a covered facility. The most you may have to do is give your rig a good rinse to get it looking great.

Longevity for Your Rig

Perhaps one of the most important benefits of underground storage is the longevity it can afford your rig. RVs tend to be one of the most difficult-to-maintain vehicles and consistently need sealing and upkeep to remain in good working condition. That maintenance is sometimes predicated on the environment the rig is stored in. If outside, ultraviolet rays from the sun can speed up the breakdown of an RV’s rubber, seals, and paint. Plus, RVs stored in cold areas can expand and contract drastically during freeze/thaw cycles, which weakens the structural integrity of the right itself. But in underground storage, where the climate is controlled and there is no inclement weather or UV rays, environmental deterioration is staved off.  

With these benefits in mind, underground storage is an option worth exploring and the cost can often fit into many RV owners’ budgets. Have you ever stored your rig underground? Let us know in the comments or contact us today!
