We’ve done some version of no-hookup camping in some genuinely uncomfortable heat. Two weeks in my cousin’s driveway in Dollar Bay, Michigan, where it hit 90 on several days. One night in a Cracker Barrel parking lot in Bay City in August where the temperature didn’t drop below 76 by 6am. And four days in Lawrenceburg, Kentucky, right off the Kentucky River, where it was 99 degrees every single day and the humidity was the kind that makes you feel like you’re breathing through a wet towel. We were camped right on the Kentucky River specifically because we wanted access to the water, and at 99 degrees with that humidity, we used every bit of it. It was the first time Frankie ever walked in voluntarily.
We have a small R-Pod 192 and a generator, but running it for AC burns through gas fast, it’s loud, and a lot of places where we boondock don’t allow them. So we’ve figured out how to manage the heat without it. Here’s what we actually do.
How to Find a Cool Campsite When Boondocking
This one costs nothing and makes a bigger difference than any gear we own. We try to find a shaded spot first. At the Cracker Barrel in Bay City, we circled the lot until we found a spot under a tree—not deep shade, but enough to keep direct sun off the roof for part of the afternoon. We also didn’t pull in until around 6pm, which meant we skipped the worst of the heat and let the asphalt cool down before we settled in.
When we can’t find shade, we put the awning out just enough to block sun from hitting the side of the trailer. Not fully extended, just positioned to keep the windows from acting like a solar collector.
Use Your RV Vent Fan to Cool the Trailer
Our R-Pod came with a 4-way bathroom vent fan and we run it any time it’s hot—all day, all night if needed. It pulls air through the trailer and exhausts it out the roof. In a small space, that continuous airflow does more than you’d expect from something that came standard with the rig.
Best Fans for RV Boondocking Without Shore Power
We keep two USB fans on the side tables, one blowing toward us from each end of the trailer. We also have rechargeable fans that charge via a small solar panel during the day, which means we’re not pulling from the trailer battery to keep the air moving and we can run them all night without worrying about it. The ceiling fan that came with the R-Pod keeps air circulating when we’re moving around the trailer.
In Bay City, the fans ran all night. It wasn’t comfortable exactly, but it was manageable.
For our daughter, we clip a stroller fan wherever she’s sitting, and we keep handheld fans around for when she’s moving between spots. Those handhelds are small enough to throw in a bag and genuinely useful anywhere you’re sitting outside in the heat.
How a 12-Volt Dehumidifier Helps in a Hot RV
We plug a small dehumidifier into the 12-volt outlet and run it during the day. In Kentucky, the humidity was bad enough that we were emptying it constantly. Instead of dumping that water, we used it to flush the black tank—why use our fresh water supply, the water we’re saving for showers, when the dehumidifier is pulling moisture straight out of the air? We figured that out on the fly and we’ve done it ever since.
Dry heat and humid heat at the same temperature are two completely different experiences. The dehumidifier doesn’t make it cool, but it makes the air inside feel a lot less oppressive.
Cook Outside to Keep Your RV Cool
When it’s hot, everything goes outside. Running the stove inside a small trailer heats it up fast and it takes a long time for that heat to dissipate. We set up outside and cook there, which keeps the interior noticeably cooler into the evening.
Keep Wet Towels Out of Your RV in Hot Weather
We don’t dry towels inside the RV when it’s hot—wet towels just add humidity to a small space. Everything goes outside on a line or over a chair. If you’re curious about our full towel setup in the R-Pod, that’s its own post: how many towels you actually need in an RV.
Take a Cool Shower Before Bed to Sleep Better
A cool shower right before bed drops your body temperature enough that falling asleep is easier, even when the trailer hasn’t fully cooled down yet. Low-tech, but it works every time. If you have an outdoor shower, you can use that to keep some of the moisture out of the RV, too.
How to Keep Kids Cool While Boondocking
Our daughter was with us on all of these trips. For her it was the same basic logic—keep air moving, keep her hydrated, dress her light. The stroller fan and handhelds helped a lot when she was sitting still. We kept a steady rotation of popsicles and ice water going through the hottest part of the afternoon, and when we had access to water, that was the best option. In Kentucky, that meant the river.
How to Keep Your Dog Cool in an RV Without AC
Frankie is not a water dog—or he wasn’t, until Kentucky. The river was the first time he walked in voluntarily, which is saying something. We waded in with him and let him cool off that way.
For day-to-day heat management, we kept his water dish filled with fresh water and added ice cubes right before he’d drink. We made frozen peanut butter and yogurt treats and gave them to him during the hottest part of the afternoon. We put ice packs under the sheet in his bed, which he seemed to genuinely appreciate. And when it was really bad, I’d soak a small towel in ice cold water and lay it on his head. He’d tolerate it for two or three minutes, just long enough to bring his temperature down. I won’t say he loved it, but he let me do it.
The biggest thing with dogs in the heat is just access to fresh water, frequently. Everything else is secondary to that.
What Boondocking in Extreme Heat Actually Looks Like
Some of this is gear and some of it is just accepting that boondocking in real summer heat is not the same as camping with hookups. Kentucky was brutal. We were comfortable enough at night to sleep, but most days we were in the river, which was the whole point of being there anyway. And some days you have to break out the generator, or just give up and find a campground with hookups. There’s no shame in that either.
