RV Maintenance Tips for Extended Stays in Texas

A weekend camping trip and a three-month work stay put very different demands on your RV. When you are living in your rig full-time — running the AC constantly, using the kitchen daily, and staying hooked up to shore power for weeks at a stretch — small maintenance issues become big ones fast.

Texas adds its own challenges: heat, humidity, UV exposure, and the occasional severe weather event. Here is what to stay on top of during an extended stay on the Texas Gulf Coast.

Inspect your shore power cord and connection at the pedestal regularly. In humid Gulf Coast conditions, connections can corrode over time. A loose or corroded connection causes voltage fluctuations that damage appliances.

• Check the plug for heat or discoloration (signs of a bad connection)
• Use a surge protector — always. Power quality at RV parks varies, and a surge can destroy your inverter, TV, or refrigerator in seconds
• A 30/50-amp surge protector with voltage monitoring is a worthwhile investment for any extended stay

Even on shore power, your house batteries are working. Check water levels in flooded lead-acid batteries monthly. Keep terminals clean and free of corrosion. If you have AGM or lithium batteries, follow the manufacturer's maintenance schedule.

If you have a generator, run it under load for 30 minutes every month to keep it in working condition — even if you are on shore power full-time. Fuel stabilizer is a good idea if it will sit unused for more than 30 days.

Always use a water pressure regulator between the park's water supply and your RV. Municipal water pressure can spike, and RV plumbing is not built for high pressure. A $15–$25 regulator set to 40–50 PSI protects your entire water system.

An inline filter between the hose and your RV improves water taste and removes sediment. Replace the filter cartridge every 3–6 months on an extended stay.

Keep your black tank valve closed until you are ready to dump — never leave it open continuously. Leaving the valve open causes liquids to drain while solids accumulate, leading to pyramid plugs that are expensive and unpleasant to deal with.

Dump your black tank when it is two-thirds to three-quarters full. Follow with your gray tank to flush the hose. Use RV-safe toilet paper only.

Inspect your water hose and sewer hose monthly. Texas UV exposure degrades hoses faster than in northern climates. Replace any hose showing cracking, brittleness, or discoloration.

Your AC is working harder in Texas than anywhere else. A few things to stay on top of:

Clean the filters monthly. Dirty filters reduce efficiency and make your AC work harder, shortening its lifespan. Most RV AC filters slide out easily and can be rinsed with water and air-dried.

Check the roof seals around the AC unit annually. The roof penetration around your AC unit is a common leak point. Inspect the sealant and reseal if you see cracking or separation.

Listen for unusual sounds. A rattling or grinding AC is telling you something. Catching a failing capacitor or fan motor early is far cheaper than replacing the entire unit.

Texas UV exposure is hard on RV roof materials and sealants. On an extended stay, inspect your roof every 60–90 days:

• Walk the roof carefully (or use a ladder to inspect from the edge)
• Check all seams, vents, skylights, and AC penetrations for cracking sealant
• Reseal any areas showing separation or cracking with appropriate RV sealant (Dicor for rubber roofs, self-leveling lap sealant for seams)

A small roof leak caught early is a minor repair. Left unaddressed, it becomes a major structural issue.

If your rig is parked for an extended period, your tires are at risk even if you are not driving:

UV degradation — Texas sun breaks down tire sidewalls. Use tire covers when parked for more than a few weeks.

Flat spotting — Tires develop flat spots when stationary under load. Move your rig a few feet every 2–4 weeks to rotate the contact point.

Pressure — Check tire pressure monthly. Temperature swings affect pressure, and underinflated tires degrade faster.

Slide-outs need regular attention on extended stays:

• Lubricate slide-out seals with a rubber conditioner every 30–60 days to prevent cracking and maintain the seal
• Inspect the slide-out floor for moisture intrusion, especially after rain
• Exercise the slides — extend and retract them fully at least once a month to keep the mechanism working smoothly

South Texas has insects. Fire ants, cockroaches, and wasps are the most common issues at Gulf Coast RV parks.

• Inspect the underside of your rig for wasp nests monthly
• Use ant bait around the perimeter of your site (not inside your RV)
• Keep food sealed and dispose of trash regularly
• Foam seal any gaps or penetrations in your RV's underbelly

Keep this list on your phone or posted inside a cabinet:

• Check shore power connection for heat or corrosion
• Test surge protector
• Check battery water levels (flooded batteries)
• Inspect water hose and pressure regulator
• Clean AC filters
• Check roof seals (every 60–90 days)
• Check tire pressure and inspect sidewalls
• Lubricate slide-out seals
• Dump tanks per schedule
• Inspect for pest activity

Staying on top of these items takes less than an hour a month and prevents the kind of expensive surprises that turn a comfortable extended stay into a stressful one.
