Hot Texas summers can push your RV to its limits. At TX RV Repair, we’ve seen how sun and heat wear down seals, damage slide outs, and overload cooling systems. If you plan to travel or store your motorhome during high temperatures, you’ll want to take extra precautions. This guide covers what to look for, how to protect key systems, and when it’s time to call in a professional.
How Heat Affects Your RV
Heat doesn’t just make you uncomfortable. It causes real wear on the RV itself. Common problems include:
- Fading and cracking on exterior surfaces
- Slide out seal shrinkage or hardening
- A/C systems running constantly
- Warped interior panels near windows or slides
- Loose caulking or sealant due to sun exposure
Slide outs are especially vulnerable. Heat dries out the rubber seals and causes misalignment. Over time, this leads to poor insulation, water leaks, and noisy operation.
Parking in the Right Spot
Where you park your RV affects how hot it gets. Always aim to park in shade whenever possible. Even partial shade helps keep wall surfaces cooler and reduces the strain on your air conditioner.
Best Parking Tips:
- Park with the largest windows and slide outs facing north or east
- Use trees, awnings, or nearby structures to block afternoon sun
- Choose campsites with airflow to allow natural cooling
Use Your Awning and Sunshades
Your RV’s awning isn’t just for light rain. In high heat, it blocks direct sunlight and provides crucial shade. Use the awning during the day, especially over doors and windows.
Add a sunshade to the awning to extend protection. These vertical screens block heat while still allowing airflow. Together, they make a major difference on the sun-facing side of your RV.
Protect Your Slide Outs
Slide outs expand living space but bring added maintenance needs. In summer, seals dry out faster, slide toppers take more UV damage, and motors may overheat.
Maintenance Tips for Slide Outs:
- Apply rubber seal conditioner monthly
- Inspect and clean slide out toppers
- Keep mechanical parts lubricated
- Don’t extend or retract slides repeatedly in high heat
If your slide out is slow, noisy, or uneven, call TX RV Repair. We handle all types of camper slide out repair, including motor issues, frame misalignment, and seal replacement.
Improve Ventilation and Airflow
Proper airflow reduces the load on your A/C and helps your RV cool faster. Stock RV vent fans often underperform. Upgrading them improves comfort immediately.
Ventilation Upgrades:
- Install a high-speed roof vent fan (MaxxAir or Fan-Tastic)
- Use cross-ventilation by opening windows on opposite sides
- Add small ceiling or portable fans near key living areas
Insulate and Block Sunlight
Most RV windows are thin and let heat in easily. Reflective insulation cuts down solar gain and helps hold cool air inside.
Insulation Tips:
- Install Reflectix or similar foil insulation in windows
- Use vent pillows to block roof vent heat
- Keep blinds closed from late morning to early evening
Maintain Your A/C System
Your air conditioner works overtime in the summer. Without proper care, it can struggle or break down when you need it most.
A/C Maintenance Checklist:
- Clean or replace filters monthly
- Clear debris from rooftop A/C coils
- Check for low refrigerant or electrical issues
- Schedule a full system check-up before peak heat
At TX RV Repair, we offer A/C inspections and repairs to keep your unit running strong through the hottest days.
Lower Heat from Daily Activities
Some activities inside your RV can raise the temperature fast. Small changes can make a big difference.
Smart Summer Habits:
- Cook meals outside on a grill or portable stove
- Limit microwave and oven use during the day
- Close windows and shades by late morning
- Switch from incandescent to LED lights
Don’t Forget Humidity Control
Texas heat often comes with high humidity. Moist air feels hotter and makes cooling harder. A portable dehumidifier can ease the load on your A/C and improve indoor comfort.
If you notice condensation on windows or musty smells, it may be time to check for leaks or poor ventilation.
Protect Your RV in Storage
If your RV will be parked for several weeks, extreme heat can still cause damage. Always store your rig with care.
Storage Tips:
- Use a covered or shaded parking spot
- Reseal slide outs, windows, and doors
- Cover tires and windshield to prevent UV damage
- Open cabinet doors inside to let air circulate
Even while parked, heat breaks down seals and finishes. TX RV Repair can reseal key areas before long-term storage.
Know When to Get Help
Some problems can be fixed on the spot. Others require an expert. Call TX RV Repair if you notice:
- A slide out that won’t extend or retract
- AC blowing warm air or shutting off
- Water leaks or cracks near slide seals
- Noise, grinding, or hesitation from slide motors
We service all makes and models and can handle repairs from minor seal issues to full slide out motor replacements.
