"We’ve been using ours in our patriot x3 camper trailer all summer. It’s really easy and it works! Our camper has a canvas pop up style tent so i was worried it wouldn’t hold the cold air in but it does. It gets so cold that we have to turn it down or off completely in the middle of the night. It’s expensive but very well worth it for the summer. “

What is Overlanding?

Overlanding is an adventure travel style where the journey itself is the primary goal. It involves traveling off-road in robust vehicles like 4x4 trucks or SUVs, embracing self-sufficiency, and camping in remote areas. Whether you're off-grid for a few days or have adopted it as a full-time lifestyle, overlanding is about relying on your preparation, vehicle, and gear while immersing yourself in new cultures, connecting with nature, and exploring destinations off the beaten path.

Many pieces of equipment enhance your overlanding experiences, like portable fridges and outdoor shower systems. However, air conditioning has always seemed like a distant dream due to its size and energy requirements. Overcoming high temperatures during rest has been a major challenge, often affecting sleep quality and becoming a barrier for family participation in these adventures. Poor sleep in high temperatures can severely impact your performance, making the next day's activities as dangerous as driving under the influence.
