We just bought our first trailer, it is a 1990 Bigfoot 1500. My question is, what do I need to attain and do to the trailer, so that I can charge the battery from the truck when towing, and from the power at the campground while camping?

Thanks

Presumably, the converter is already wired into the trailer electrical system to provide some charging to the battery when plugged into shore power. Keep in mind that a 1990's converter will likely not have a very good battery charger in it, so don't try to maintain the battery that way in long-term storage.

For tow vehicle recharging, you will need to have a wire (with circuit breaker) attached to the TV battery and then run all the way back to the trailer connector. On the trailer side of the connector it will have to be connected to the 12VDC system.

If you have a 12VDC mode on your fridge, it would be wise to install a relay or isolator that won't let 12VDC from the tow vehicle go to the trailer unless the ignition is switched on -- Otherwise, if the fridge is in 12VDC mode, it can quickly run down both the egg and tv batteries.

Lots of info in the archives about all this.

Thanks. I have checked for power on the 7 pin and have no power. Looked for the fuse in the box under the hood but, could not see one. The truck is a 2001 Silverado 1500 with Trailer Package.
