Truck campers can be kept cool by parking in the shade, higher elevations, or forested areas
Truck campers can be kept cool by parking in the shade, at higher elevations, or in forested areas.
Parking in the Shade
Parking your truck camper in the shade can make a big difference in the overall temperature inside the camper. Trees, mountains, and canyons are great ways to get shade, but they may not always be available. This is when a good awning or canopy comes in handy by bringing the shade to your campsite when it’s lacking.
Camping at Higher Elevations
Camping at higher elevations is another way to beat the heat. In states like California, Arizona, New Mexico, and Nevada, camping at elevations higher than 7,000 feet can help you stay cool. Even higher elevations may be needed depending on weather patterns.
Camping in Forested Areas
Forested areas tend to be cooler than open spaces. Camping in a forested area can help you stay cool during hot weather.

A generator is required to run an air conditioner in a truck camper
RV air conditioners typically have ratings of 15,000 BTU or 13,500 BTU, and require a generator with a capacity of 2,000 to 4,000 watts. A 15,000 BTU air conditioner will need a generator with a capacity of 3,000 to 4,000 watts, while a 13,500 BTU air conditioner can be powered by a 2,200 to 3,000-watt generator.
It is important to note that the generator must also be able to handle the starting and running requirements of the air conditioner, as well as any other appliances that will be connected to it. The starting wattage of an air conditioner is usually higher than the running wattage, and this should be taken into account when choosing a generator.
In addition to the generator, an RV air conditioner also requires pre-wiring and a suitable installation process to ensure safety and proper functioning.

Swamp coolers are effective in dry climates
Swamp coolers, also known as evaporative coolers, are an effective alternative to traditional air conditioners in dry climates. They are based on the principle of evaporative cooling, which has been used since ancient times. When hot, dry air passes over or through water, it cools off, and swamp coolers use this natural process to lower the temperature of the surrounding air.
Swamp coolers are particularly effective in dry climates because they rely on the evaporation of water to cool the air. In humid environments, the air is already saturated with moisture, so the evaporation process is less effective, and the cooler may even contribute to the humidity, making the room feel damp and uncomfortable. However, in dry climates, there is room for the air to absorb more moisture, allowing the swamp cooler to effectively lower the temperature.
The US Department of Energy (DOE) confirms that swamp coolers can reduce the ambient temperature by 5 to 15 degrees Fahrenheit, but only in areas with low humidity. This makes them ideal for warm, arid regions such as the American Southwest, where the dry air can readily absorb moisture.
Swamp coolers offer several advantages over traditional air conditioners. They are significantly cheaper to buy and operate, using 60-80% less electricity than standard air conditioning units. They are also more environmentally friendly, as they do not use refrigerants or contribute to global warming. Additionally, swamp coolers can increase humidity in dry climates, making the air more comfortable and helping with perspiration.
However, swamp coolers do have some limitations. They require regular maintenance, including cleaning or changing the pads to prevent odours and air quality issues. They also need a steady supply of water, which can be challenging in the hot, dry climates where they are most effective.
Overall, swamp coolers are a cost-effective and environmentally friendly option for cooling in dry climates. By harnessing the power of evaporation, they can effectively lower the temperature of the surrounding air, providing a welcome respite from the heat.

A rooftop air conditioner requires professional installation
Installing a rooftop air conditioner on a truck camper is not a simple task and requires careful planning and execution. Here are some reasons why professional installation is recommended:
Weight and Size of the Unit
Rooftop air conditioners for truck campers can weigh around 90 pounds, and the packaged shipment can weigh up to 160 pounds. Lifting and maneuvering such a heavy unit onto the roof of a truck camper can be challenging and may require scaffolding or other specialized equipment.
Electrical Knowledge and Skills
Installing a rooftop air conditioner involves complex electrical work, including wiring, circuits, and electronics. It is crucial to have a good understanding of electrical systems and safety protocols to ensure a proper and safe installation.
Pre-existing Conditions and Compatibility
Before installing a rooftop air conditioner, it is essential to check if the truck camper has pre-existing conditions that may impact the installation. This includes ensuring that the camper is pre-wired for an air conditioner and has a suitable breaker. Properly assessing and addressing these factors requires knowledge and experience.
Proper Sealing and Installation
Installing a rooftop air conditioner involves removing the existing roof vent and creating a proper seal for the new unit. This process requires careful removal of old caulking and cleaning of the roof surface. Incorrect sealing can lead to water intrusion and potential damage to the camper.
Safety Considerations
Working at heights and handling heavy equipment pose safety risks. Professionals have the training and experience to navigate these challenges safely and effectively. Additionally, they can guide you through any potential hazards associated with the installation and provide advice on safe usage and maintenance.
In conclusion, while it is technically possible to install a rooftop air conditioner on a truck camper, it is a complex and potentially dangerous task. Engaging a professional installer ensures that the job is done correctly, safely, and in compliance with any relevant regulations.

A window air conditioner can be mounted on a plywood tailgate
Installing a window air conditioner is a simple DIY project. It requires minimal heavy lifting and tightening a few screws. Here is a step-by-step guide on how to mount a window air conditioner on a plywood tailgate:
Step 1: Take Measurements
Measure the width of your air conditioner, including any vents that stick out on the side. Also, measure the height of your air conditioner, which should be the box height and not include the lips on the top or bottom. Next, measure the height of the window opening by measuring right up against the window to get the shortest height.
Step 2: Cut the Frame Lumber
Using the measurements from step 1, cut your 2x4s as follows:
- Cut three pieces to the width of the air conditioner (including vents).
- Cut two pieces to the height of the window frame.
Step 3: Start the Frame
Lay one of the shorter pieces of 2x4 down and screw the ends of the longer pieces to its ends. Create a rectangle by screwing the other short piece of 2x4 between the long pieces at the other end. Ensure the corners are square. Dry fit the rectangle into the window opening to make sure it fits snugly.
Step 4: Finish the Frame
Dry fit the air conditioner into the frame, with the bottom lip against the outside of the frame. You will notice that the top lip is probably U-shaped, with the backside being shorter. The last piece of 2x4 will sit across the top of this shorter leg of the U. Lean the air conditioner so that the front vertical piece of the top lip lines up with the front edge of the wood frame. While holding this position, mark the placement of the last piece of 2x4 on the frame. Remove the air conditioner and screw this piece of lumber in place. Dry fit the air conditioner again to ensure a proper fit.
Step 5: Cover the Top of the Frame
Measure the opening at the top of the frame and cut a piece of plywood to cover it. Screw the plywood covering in place. Optionally, you can staple screening material over the side of the frame facing outside and hinge the plywood to allow for opening the window when desired.
Step 6: Installation
Open the window and slide the frame inside, up against the window framing. For added stability, screw the frame into the window framing and/or use angle brackets. Slide the air conditioner into place and secure it by screwing through the lip. Extend the accordion panels from both sides of the air conditioner to the window sash track and secure them with screws. Cut and insert a foam insulating strip between the upper and lower window sashes. Plug in the air conditioner, turn it on, and enjoy the cool air!
