To turn the 7-way on your truck into a 12v power source you will want to use the Pollak 7-Way to 12 Volt Power Outlet Adapter item # PK11896. This will plug into a 7-Way on your vehicle and provide a 12V plug on the other end that can be used with 12V accessories. This adapter can handle a 20 to 30 amp power draw but the limiting factor will be if the 7-Way on your truck is rated high enough as well. You will want to check the fuse for the 12 volt circuit for the tow package trailer connector to make sure it is rated high enough to power your cooler.

If your cooler requires a standard 110V AC plug you will need to install the Power Inverter 1000 Watts with Three AC Receptacles item # WC3720.

There is not a 110V AC power outlet available that is able to plug directly into a 7-Way.

Since the pin weight of your camper is 2.1k, I recommend going with the LoadLifter 5000 opposed to the 7500. While technically there is not reason you couldn't use the 7500 kit, it really is not necessary for a camper like yours. Generally the…

You will have to go with a sliding hitch to allow the trailer to make tight turns. For a trailer 8 feet wide the only bed length that's going to allow 90 degree turns without a slider is a stationary hitch. That being said you have two options.…
