Help! No Power, Even when Plugged into the truck
I'm a newbie, and we just drove 5+ hours to our destination. Along the way, we used the toilet, and the lights were fine. Now we're here and there's no power, even when plugged into the truck. The battery reads 12.6 V. What happened and how can it be fixed?

Check battery disconnect, battery cables, in line fuses and fuse panel

Are you plugged into shore power? Is the shore power working? Are all your AC breakers on? If on generator be sure the gen breakers are on. Are you in a MH?. If so is the battery disconnect on? I can't find my Karnack hat. Need more information. Lights are 12 volts. Outlets and most equipment is 120 and/or Gas.

check your 30 amp fuse located near your battery, 99% of the time that's the problem

Thank you all. We're not plugged into shore power. I checked each one of the fuses, the battery lines, and connectors and all looks good. This is a 174BH travel trailer and the underbody is enclosed so I can only see so much, and I'm not seeing an inline fuse. Is this less obvious than I would expect?

Look for a inline fuse near your battery, along the trailer tongue. Follow wires from the battery back.

Now I've got it working when the truck is on, I guess maybe there was a loose connection, but still it won't work just from the battery. I'm just not seeing an inline fuse, but maybe I'm missing it in plain sight. I've attached a picture of all the visible wires comingoff of the battery.

The two things under the red caps are circuit breakers, you don't have a fuse. If you are getting power to everything while hooked to the truck then it has to be a bad connection at the battery.

That makes sense to me, but the battery terminal connections are fully attached. Maybe there's somewhere else I'm not checking?

Yes. I is within 6' of the battery under the tong.

Do you have power on both sides of both circuit breakers? One could be bad, do you have a meter?

You must have a voltmeter and the trouble shooting skills to find these problems easier.

Solved!
Just wanted to report back that the problem is solved. It was a loose ground wire in the junction box. Everything felt snug but I took a wrench and a screwdriver to all of the wire connections and tested after I tightened each one. That was a way easier fix than I was expecting!
I appreciate all the help!

On RV's many electrical problems refer to bad grounds, as they come from the manufacturer without any die-electric grease on the chassis connection. Corrosion will take place very quick depending on environment conditions. In general there are at least 3 chassis ground connection, but larger may have more.
So if all visible connections and fuses are OK >>>>check the GROUND Connections.
Usual one up front and the rest would be under the panel on the chassis.
