Some say Dodge has a relay, others say only Ford and Tundra. In this instance "enblethen" and "skipnchar" posted opposing statements just one hour apart. Someone has to be wrong. It would sure be nice if people who don't know would not post.

I have seen some Dodges with relays and others without.
Martipr: look under the hood on the driver's side wheel well in the fuse and relay box. It will physically tell you whether you have relay controlling trailer power.
Fords have relays.
I THINK that my 2006 Dodge 2500 Ram Diesel is NOT hot all the time. I have tested it with a test light. However, I always unplug the trailer (and the GPS etc.)if I am stopping overnight with the trailer connected to the Ram. I sleep better not think about if it is hot or not.
Please give me enough troubles, uncertainty, problems, obstacles and STRESS so that I do not become arrogant, proud, and smug in my own abilities, and enough blessings and good times that I realize that someone else is in charge of my life.
If it's the truck in your signature, it will draw from the truck battery. Fords don't let that happen unless the key is on. It shouldn't be a problem for one night. It will charge as you drive, but will take many miles to recharge your trailer battery. I always unhook the umbilical cord if I stay hooked up just to be safe.
X2. Some people with GMs that had alternator/battery issues actually charged their truck battery with the converter in the trailer overnight at a campground with hookups by leaving it plugged in overnight. I have played with my Ford using a meter and as soon as the key is turned off, that's it on that pin in the connector.
As for charging while driving . . . not much. I towed my TT home 2.5 hours and plugged it in here at the house. It still took an hour and a half for the charger to get to the float stage on my batteries.
