How to Keep House Batteries on Slide-In Truck Camper Charged

Question

Question:

I want to wire my slide in camper so the alternator from my truck charges the house battery in the camper. I dont need tail lights and brakes, only battery charger. Do I just hook up the power and ground from the truck to the camper? Thanks

You could use the 12-V feed from the trailer connector to maintain the house battery on your slide in camper, but due to the ~16 ga wire feeding that circuit, you'll be able to maintain the battery but won't be able to fully charge it once it's depleted, unless you use shore power and a charger like # 329-GENIUS10.

In order to deliver a full charge, I'd recommend using a DC to DC charger like # 331-BCDC1225D for 25A or # 331-BCDC1240D for a 40A charger.

I've linked to product videos for the chargers I mentioned above.

I have a solution for you, but the NOCO GEN1 charger you've mentioned is not currently available and has been replaced by NOCO. Instead you could use a single bank charger like the NOCO Genius 12v 10amp #NOC44FR, which is the newer version with…

I have two components that will work together to do what you're hoping, but there isn't an all in one option that pulls power from your truck and also plugs into shore power. For the DC I recommend the BC-DC Charger #RED96FR which is good for…

There are a number of factors involved when converting a semi 7-way to an RV 7-way. Semis generally use a 7-pin round pin socket, similar to #PK11720. And RV style 7-way uses blades, like #PK12706. We do not offer any pre-made adapters to make this…

We do offer the Trailer Connector Adapter, #HM47425, which converts a 7-pole round connector to a 7-pole flat connector. This adapter works for tow vehicles with combined taillight wiring, meaning that the turn signals and brake lights run on the…

Either way is correct. It depends on if you want to keep the semi-style 7-Way (if you need to tow that type of trailer) or if you will never be towing a semi-trailer. If you need to keep the 7-Way semi active on the truck, then you would need to make…

You certainly can! Installing a brake controller is fairly easy if you are familiar with running wiring. To install a brake controller like the popular Tekonsha Prodigy P3 #90195 you will need to run the wires on the pigtail to the following…
