(And without melting yourself in the process.)

RVing in triple-digit heat isn’t just uncomfortable—it’s hard on your rig. Air conditioners struggle, appliances overheat, and your batteries, tires, and roof all suffer under the relentless sun.

Here’s how to survive (and thrive) when the mercury hits 100+—without cooking your electrical system or sanity.

☀️ 1. Park Smart: Shade Isn’t Optional

  • Look for trees, north-facing sites, or buildings that block afternoon sun

  • If possible, orient your rig so the refrigerator side is in the shade

  • Use Reflectix, thermal curtains, or vent covers to block heat

Bonus Tip: A portable shade cloth on the sunny side can drop inside temps by 5–8 degrees.

❄️ 2. Support Your A/C—Don’t Just Crank It

Your RV A/C wasn’t built for Arizona death rays. Help it out by:

  • Running fans to circulate air (especially at night)

  • Cleaning or replacing the A/C filter weekly in dusty areas

  • Using dehumidifiers or moisture absorbers—yes, even in dry heat

  • Running a second A/C only when plugged into proper 50-amp power

🔋 3. Be Mindful of Your Electrical Load

When it’s 105°F and your fridge, A/C, water pump, and microwave are all running… that’s a lot.

  • Don’t overload a single circuit

  • Use a surge protector and voltage monitor

  • If the park power is sketchy, don’t run both A/Cs at once

🚿 4. Switch to “Desert Mode” Living

  • Shower at night to lower core body temp

  • Cook outside or prep cold meals (save your interior from extra heat)

  • Travel early and settle by 11am to avoid peak engine strain

🧠 5. Watch for Heat Stress—In You and Your Rig

Human signs: Dizziness, headaches, dry mouth = get cool fast
Rig signs: Breaker trips, flickering lights, strange fridge behavior = reduce your load or move to shore power

Final Thoughts

RVing in extreme heat is totally doable—you just have to plan smarter, park wiser, and respect what your rig can (and can’t) handle.
