Summer in Las Cruces means long days, bright sunshine, and temperatures that can easily climb into the triple digits. That kind of heat can be tough on your RV, especially when it sits outside for days or weeks at a time.A little preparation can help protect your interior, reduce heat buildup, and keep your RV more comfortable when you are ready for your next trip. Here are a few practical ways to keep your RV cooler during the New Mexico summer.

Park Under Covered Storage

One of the best ways to reduce heat inside your RV is to keep direct sunlight off the roof and windows.Covered RV storage helps provide shade during the hottest part of the day, which can reduce the amount of heat absorbed by your roof, seals, tires, dashboard, furniture, and other interior surfaces.Premier RV & Boat Storage in Las Cruces offers covered storage spaces designed to help protect your RV from the intense New Mexico sun, blowing dust, and changing weather conditions.

Use Reflective Window Covers

Your RV windows can let in a large amount of heat. Reflective sunshades, insulated window covers, or blackout curtains can help block sunlight before it heats up the inside of your RV.Pay special attention to the windshield and any large windows that receive direct afternoon sun. Make sure all curtains, blinds, and shades are closed before placing your RV into storage.

Cover Your Roof Vents and Skylights

Roof vents and skylights allow sunlight and heat to enter from above. Insulated vent cushions are an inexpensive way to reduce heat buildup while your RV is parked.These cushions can also help keep cool air inside when you are using the air conditioner during your next camping trip.

Check Your Roof and Window Seals

The New Mexico sun can dry out sealants and weather stripping over time. Cracked or damaged seals can allow hot air, dust, and moisture to enter your RV.Inspect the areas around your roof vents, windows, doors, air-conditioning units, and exterior seams. Repair damaged seals with products recommended by your RV manufacturer.Regular inspections can also help prevent expensive water damage during monsoon season.

Protect Your Tires

RV tires can take a beating from direct sunlight and extreme heat. UV exposure can cause the rubber to dry out and crack, even when the tires still have plenty of tread.Use properly fitted tire covers while your RV is parked. You should also check the tire pressure before and after long periods of storage because temperature changes can affect inflation levels.

Allow for Safe Ventilation

A small amount of ventilation can help reduce trapped heat, but open vents can also allow dust or rain to enter.RV vent covers can allow you to leave certain roof vents slightly open while still providing protection from the weather. Never leave windows or vents open unless they are designed to remain open safely during storage.

Remove Heat-Sensitive Items

Before storing your RV, remove anything that could melt, leak, warp, or become damaged by high temperatures.This may include:
  • Candles
  • Aerosol cans
  • Electronics
  • Batteries
  • Food
  • Medications
  • Cleaning products
  • Pressurized containers
  • Cosmetics and toiletries
Even with covered storage and window shades, the inside of an RV can become extremely warm during July and August.

Use Moisture Absorbers

It may be dry in southern New Mexico most of the year, but moisture can still collect inside an RV, especially during monsoon season.Moisture absorbers can help reduce musty odors and protect cabinets, mattresses, upholstery, and other interior surfaces. Check and replace them regularly if your RV will remain in storage for an extended period.

Maintain Your RV Batteries

Extreme heat can shorten battery life and increase the rate at which batteries lose their charge.If your RV will be parked for several weeks, follow the manufacturer’s recommendations for disconnecting, charging, and maintaining the batteries. Premier RV & Boat Storage also offers spaces with access to power, making battery maintenance more convenient for qualifying storage spaces.

Keep the Refrigerator and Cabinets Open

After cleaning and emptying your RV refrigerator, leave the refrigerator and freezer doors slightly open. This allows air to circulate and helps prevent mildew and unpleasant odors.Cabinet doors, closets, and interior storage compartments can also be left slightly open to improve airflow.

Wash Your RV Before Storage

Dust, bugs, tree sap, and road grime can become harder to remove after sitting in the summer sun.Wash and dry your RV before storing it. A quality RV wax or UV-protective treatment can provide an additional layer of protection for the exterior finish.
