Itasca Creek RV Park is located in Hill County, in Central Texas, where summer temperatures regularly exceed 100°F and overnight lows stay above 75°F for weeks at a time. The park is 3 minutes off I-35W on FM 67, and its covered sites have steel canopies that keep you cool in the summer and dry in the winter. This guide covers the practical strategies that actually work for RVers in Central Texas heat, not the generic summer tips you'll find everywhere, but the specific approaches that matter when it's 105°F and your AC is working overtime.
Site Selection Is the Most Important Decision
The difference between a covered site and an uncovered site in Texas summer is not aesthetic. It's functional. A metal carport structure over your rig intercepts direct solar radiation before it reaches your roof, dramatically reducing the thermal load your AC unit has to overcome. An RV roof in direct Texas sun can reach 160°F+. A covered site roof temperature might be 110°F. Your AC compressor notices the difference.
When choosing a covered site, look at the orientation: a cover that blocks afternoon sun (from the southwest, roughly 1pm-6pm) is more valuable than one that blocks morning sun. Afternoon sun at 95°F is harder to cool against than morning sun at 80°F.
If covered sites aren't available, position your rig so the slide-out sides face east or west (not south). The long axis of the rig catching the afternoon sun rather than the full broadside is a meaningful improvement.
Power Management: Shore Power Is Non-Negotiable
Running a large diesel generator all summer is expensive and noisy. Texas summer in an RV is a shore-power situation: 50-amp hookup, solid incoming voltage, and enough spare capacity for two AC units plus other loads.
Before you commit to a park for summer, ask: what's the shore power voltage stability? Parks with aging infrastructure or sites at the far end of long runs can see voltage drop to 105-108V under heavy load, enough to stress your AC compressors over time. A Progressive Industries surge protector with voltage monitoring will tell you exactly what you're getting.
50-amp service is the minimum for Texas summer in a rig with two roof ACs. A 30-amp hookup running dual units under load is a thermal cycling nightmare: units will trip breakers or fail to reach setpoint.
At Itasca Creek, every site has 30-amp and 50-amp electric service. Running two roof ACs? Plug into 50-amp at any site, and call us at (254) 266-2344 if you have questions.
Roof Insulation and Vent Fans
If you're spending a summer stationary, foam board insulation cut to fit over skylights and roof vents reduces solar heat gain meaningfully. 1-inch polyiso board from a home improvement store, cut to fit inside the vent frames, can drop interior roof temperatures by 10-15°F on the hottest days.
Maxxair or Fan-Tastic vent fans in existing roof vents are one of the highest-ROI upgrades for summer comfort. On a day when outdoor temps drop below interior temps (early morning, late evening), a vent fan pulling cool air through dramatically outperforms an AC unit for comfort and cost. Run the fans hard from 5-9pm to dump retained heat from the afternoon; then close up when exterior temp climbs above interior.
Window Management
Radiant heat through windows is the underestimated summer challenge. Standard RV blinds do very little to block solar radiation. They block light, but the glass still transmits heat. Reflective window insulators (the mylar-type covers used for windshields) in every window that faces afternoon sun can reduce interior temperatures by 5-10°F on the hottest days.
The windshield is the biggest solar gain surface in most rigs. A good reflective windshield cover every day, all summer, not just when parked. Your morning AC cycling appreciates it.
Timing Your Life Around Texas Summer
This is the underrated strategy: stop fighting the Texas afternoon and embrace the Texas morning. The best time in Texas from June through September is 6-10am. Dogs get their walks, outdoor cooking happens, pools are uncrowded. From 11am-6pm, you're inside. From 7pm-midnight, it's back to comfortable: outdoor seating, evening walks, cooking on the grill.
RVers who resist this schedule (trying to do outdoor activities at 2pm in July) are miserable. RVers who accept it find Texas summer surprisingly manageable.
The Pool Matters More Than You Think
A park with a maintained, temperature-controlled pool transforms the Texas summer experience. Even a 30-minute midday pool session resets your body temperature and makes the afternoon rig time comfortable rather than just endured. When evaluating summer parks, ask whether the pool is heated in winter (useful) but also whether it's chilled or shaded in summer (far more useful for most RVers).
Heat Emergency Plan
Every Texas summer RVer needs one: what do you do if your AC fails on a 105°F day? The plan should include: where the nearest hotel is (Hillsboro, a short drive away, is the closest bigger town), where the nearest RV service technician is (the park area has RV repair, including mobile service), and what the backup cooling options are (portable AC units are worth keeping in a storage bay for emergencies). The most important step is having this plan before you need it.
