Old South residents have a saying: “The weather is close today.”

According to a New Orleans friend of mine, that means the temperature and humidity are jus’ ‘bout th’ same. Example: 92 degrees Fahrenheit, 88% humidity.

If the mention of muggy, stifling heat makes you reach for the nearest neck cooling pad, you’re not alone. Around June, many RV owners wonder, “What’s the most efficient RV air conditioner?”

• Wash a white TPO or EPDM roof to reduce solar heat gain.
• Install sunshades or reflectix covers (with stick-on velcro) in windows and below ceiling fans.
• Use D-bulb foam seal around doors and window frames to eliminate seam drafts. Use canned spray foam around underbelly penetrations and fender wheel openings.
• Screw foam board to the underside of your floor, or install skirting around the base of your motorhome or fifth wheel.
