There’s nothing like RV camping by the beach. The sound of the waves, salty breezes, and sand between your toes. But while your soul might be soaking up the sunshine, your RV? It’s quietly taking a beating from all that coastal charm.

Between the salt in the air and the sand in... well, everything, beachside RV camping requires a little extra care to keep your rig in top shape.

Here are some essential beach-friendly RV maintenance tips to help you enjoy your coastal camping getaway without sacrificing your RV’s longevity:

1. Rinse Off the Salt Frequently

Salt air is highly corrosive, especially to metal parts on your RV. After a few days parked near the beach (especially on windy days), your RV can collect a fine layer of salty residue.

What to do:

Give your RV a thorough rinse with fresh water at least once a week when camping near the coast.
Use a hose to spray undercarriages, wheel wells, and around door hinges and slide-outs.
Avoid harsh detergents—just clean, fresh water will help prevent corrosion.

2. Protect Seals, Windows & Rubber Components

Salt and sun are a damaging duo when it comes to rubber seals and weatherstripping.

Quick tip:

Apply a UV and salt-resistant protectant (like 303 Aerospace Protectant) to door and window seals.
Check for cracks or drying, and reapply protectant every 4–6 weeks during beach trips.

3. Keep Sand Outside (As Much As Possible)

Sand has a sneaky way of getting everywhere: floors, storage bays, bedding, and even inside appliances. It can scratch surfaces and gum up slide tracks.

Prevention tips:

Set up an outdoor rug or mat near your RV entrance.
Keep a small broom or battery-powered vacuum handy.
Designate a “sandy shoe bin” outside the door—and maybe a rinse bucket for feet!

4. Watch the Undercarriage

The bottom of your RV is often “out of sight, out of mind,” but it’s a prime spot for salt buildup and corrosion.

Best practice:

After your beach stay, visit an RV wash with undercarriage cleaning.
Inspect axles, jacks, and frame rails for early signs of rust.
Consider applying a rust inhibitor or undercoating for long-term protection.

5. Check Roof & Vents Often

Beach winds carry debris and salty moisture up and over your RV roof. Over time, this can wear down seals and vent covers.

Maintenance musts:

Inspect your roof before and after each beach trip.
Clear off leaves, sand, or shells.
Reseal any trouble spots and double-check fan vent covers for cracks or warping.

6. HVAC Care in Humid Air

Beach humidity can make your A/C work overtime—and salt can damage coils if left unchecked.

Stay cool by:

Cleaning or replacing air filters before and after beach trips.
Rinsing A/C coils (gently!) to remove salt buildup.
Running a dehumidifier inside the RV to reduce moisture and mildew risk.

7. Don’t Forget the Tow Vehicle or Motorhome Engine

If you’re hauling your RV, your tow vehicle needs love too! Salt affects brakes, hitches, and suspension components.

Post-beach checklist:

Wash and inspect your vehicle.
Rinse out the hitch area and apply lubricant.
Check your brake lines for corrosion.
