This is sort of Dodge Ram specific, but I got out my Fluke meter and checked the seven way plug socket today on my 2016 Ram 1500 diesel. There is 12 volt power always on when the tow vehicle is shut off-even after all the various timers that keep the lights, etc. on after ignition shutoff have shut down.

 

Why is this important? Because the tow vehicle will continue to provide 12 volt power to the Casita and if enough time passes by, could run down the starting battery on the truck, which would Be A Bad Thing.

 

So, when stopping for the night or out boondocking, it's best to disconnect the brake and light cable, but it also might be a good idea to put a post-it on the dash to remind you to hook it back up when you get ready to depart. Myself, it's an item on my "pre-flight" walkaround inspection, but your procedures may be different.

Good advice.  I always disconnect my truck and trailer when stopped at night.  Also.......we always check the lights on trailer anytime we reconnect or when starting out each morning......just a habit that ensures lights are working properly.

When I tow with My 2004 Nissan Frontier, I disconnect my 7-Pin connector because the plug is still energized even when it's off, but when we tow with my wife's newer 2016 Chevy Silverado, it isn't necessary to unplug because it has an automatic disconnect solenoid that kills power to the trailer when the ignition is off. Some of that new technology...

I had an 08 2500 Chevy - the charge wire stayed hot all the time. The 15 F150 the charge wire goes cold when cut off. The 08 Chevy wire was quite a heavy gauge wire and would run the fridge with no problem. The 15 F150 will not run the fridge while driving.

i killed both batteries in my old 1995 ford ranger and 2013 casita twice when i initially purchased my trailer 3.5 yrs ago because i failed to unplug them, the second time when i had stopped at walmart for a couple of hours! replaced the ranger in 2015 with a new toyota tacoma that shuts down the power to the casita once the ignition is off. i still usually unplug when stopped overnight, but not always.  it's easy to check your 7 pin connector in the tow vehicle to see if it stays hot with ignition off or not. the recommendation is that you should unplug if you plan to be gone for 30 minutes or more, if your tow plug remains hot.

Brand new Dodge Durango has a note in with the brake controller pig-tail that power is always on.

Will I remember to unplug?

We'll see.

Be sure to wait a few minutes after shutting off the tow vehicle (or check before starting the vehicle) to see if there is power on the 7 pin connector.  Some vehicles keep the connector hot for a minute or two after shutting down, then open the connection.

Your mechanic can put a relay to stop power when you turn the ignition off. Relatively cheap.

We always unplug when we've set up camp. We also always do a light check when we hook up. I don't know if our Tundra's 7 pin is hot all the time..that's probably a good thing to check. Nevertheless, we'll still completely disconnect.

When stopped for lunch or dinner, I turn the frig off.  The frig kills the battery in about 2 hours.  Since I added an 80 Watt solar panel, that provides just enough power on a sunny day to keep the frig going on DC for the time I'm in the restaurant.  But I still turn off the frig.  I also installed a safety storage connector for the trailer side of the power, brake, turn signal cable.  I drove off once with it disconnected and had to replace the whole thing.

Eek, I've always wondered about that happening. Yikes, I bet that wasn't a cheap lesson.... :(

I unplug the brakes/light cable and tie a a long orange plastic ribbon to the steering wheel, like sort of a "remove before flight" reminder to plug it back in. I do the same if I leave the power cable plugged in at the campsite as I get ready to leave-to stay cool just a bit longer....I also put an orange traffic cone on top of the cable that I will immediately spot in my mirror. Expensive lessons are the best.
