Slide-In Camper Electricity: Easy Connection Guide

Slide-in campers are a great way to turn your truck bed into a mobile home. But how do you power these campers? There are a few ways to connect electricity to your slide-in camper. One way is to use shore power and operate the slide mechanism with that. Another way is to run a generator to move the slide-out room. Finally, you can start your truck and run the slide mechanism with the power from your vehicle. If you have a 7-way trailer connector at the back of your truck, you can get an extension that will run from the connector up to your camper's plug. If you don't have any kind of trailer connector on your truck, you'll have to add wiring and a connector.

Connect camper to shore power

Shore power is a great way to power your slide-in camper. Here are some detailed instructions on how to connect your camper to shore power:

First, locate a power source. This could be an electrical outlet at a campsite or a generator. If you're at a campsite, simply locate the power pedestal, which is usually a metal box with electrical outlets. If you're using a generator, place it in a well-ventilated area and ensure it has enough fuel to run.

Next, you'll need a power cord, also known as an extension cord, to connect your camper to the power source. Make sure the cord is designed for outdoor use and is in good condition, with no cuts or tears. The cord should have a plug that matches the outlet on the power source. If they don't match, you may need an adapter.

Now, carefully connect one end of the power cord to the power source. If you're plugging into a campsite power pedestal, make sure the breaker is turned off before plugging in. Once plugged in, you can turn the breaker back on.

With the power cord connected to the power source, it's time to connect the other end to your camper. Locate the electrical inlet on your camper, which is usually on the exterior of the vehicle. This is where you'll plug in the power cord. Make sure the connection is secure and that the plug is fully inserted into the inlet.

Once everything is connected, you can turn on the power at your breaker box or generator. Your camper should now have electricity flowing to it. You can test this by turning on lights or appliances inside your camper.

It's important to note that shore power typically provides 120-volt electricity, which is standard for most appliances and outlets. However, always check your camper's manual to ensure you're using the correct power source and that your electrical system is properly set up.

Additionally, be mindful of the amperage rating of your power source and the electrical devices you're using. Don't exceed the amperage capacity of the power source to avoid overloading it.

When connecting to shore power, always prioritize safety. Ensure that all connections are secure and that there are no signs of damage or wear on the power cord or electrical components. If you notice any issues, have them inspected and repaired by a qualified technician before use.

By following these instructions, you'll be able to safely and effectively connect your slide-in camper to shore power, keeping your home-away-from-home comfortable and powered up.

Use a generator

If your slide-in camper's battery is dead, you can use a generator to operate the slide mechanism. Here are some detailed instructions on how to connect your slide-in camper to a generator:

First, ensure that you have a suitable generator for your camper. The generator should be rated to supply enough power for your RV's electrical system. For a 30-amp RV, a minimum of a 3,500-watt generator is recommended, while for a 50-amp RV, a 6,000 to 8,000-watt generator is recommended for dual ACs, and 10,000 to 12,500 watts for three ACs.

Next, check your RV's power plug type. Most RVs use either a 30-amp or 50-amp plug, but some smaller campers may have a standard 15-amp or 20-amp household plug. You will need to purchase an adapter to connect your RV to the generator if they have different plug types. For example, if your RV has a 30-amp plug and your generator has a 15-amp outlet, you will need a 15-amp to 30-amp adapter.

When connecting the generator, make sure it is placed on a level, flame-resistant surface, such as a concrete RV pad, at least 15 feet away from your RV. Ensure the generator has plenty of clearance, with at least five feet of airspace on all sides, and that the exhaust is pointing away from your RV and any neighbouring campers to prevent carbon monoxide poisoning.

Before starting the generator, check the oil level and ensure it has enough fuel. If you have a portable generator, you may also need to check and clean the air filter if it has been stored for a long time. Turn off all RV appliances and make sure any backup fuel or oil is stored at a safe distance from the generator.

Now, you can start the generator. Consult your owner's manual for specific starting procedures, as they may vary depending on the generator model. Once the generator has been running for at least five minutes, you can plug in your RV power cord. If your generator has a crank handle, you may need to use a surge protector and plug your RV power cord into the surge protector first before connecting it to the generator.

When disconnecting the generator, always turn off all RV appliances first, then disconnect the power cord, and finally, power down the generator following the instructions in the owner's manual.

Some important safety reminders: always refuel the generator when it is turned off and allow it to cool down for at least five to ten minutes before refuelling. Use the correct type of fuel as specified in the owner's manual to avoid engine damage. Be mindful of noise restrictions and curfews at campgrounds, and try to keep the generator's noise level below 50-70 decibels to avoid disturbing your fellow campers.

These alternative power sources can supplement the power from your truck, ensuring your camper has a stable and sufficient electricity supply.

By following these steps, you can safely and effectively connect your camper to your truck's power supply, ensuring a reliable electricity source for your home on wheels.

Install solar panels

Installing solar panels on a camper can be done in a variety of ways, but here is a step-by-step guide on how to do it using 3M VHB tape (no holes!). This method is recommended for a new van, but not for an older vehicle. The 3M VHB tape will hold the solar panels in place, so if the paint chips off, the panels may come loose and cause harm.

First, test all components to ensure they are functional. Next, pre-install the brackets on the solar panels, relocating them to the inside edge to minimize the gap between the panels. This will make them less visible from the ground. Then, install the 3M VHB tape on the brackets, ensuring the application temperature is at least 60°F.

Trim out the MC4 connectors from the extension cables to allow them to be routed through the roof and connected to the Victron MPPT solar charge controller. Pre-fit the solar panels on the roof and mark their exact location. Drill holes for the cable glands or entry box, breaking any sharp edges and smoothing the surfaces. Apply primer, paint, and clearcoat to protect bare metal from rusting.

Install the solar panels on the roof, connecting all cables and ensuring they are routed in a way that won't rub against the roof. Route the extension cables through the roof and clean the roof with isopropyl alcohol before peeling off the 3M VHB tape and pressing firmly to adhere. Fasten the glands to the roof and seal all brackets and glands with Dicor Lap Sealant.

Finally, check that there is voltage coming from the panels.
