Running fridge while driving
I want to load up my fridge at home. It is a 3 way fridge. Will the battery be charging from my truck? How long typically will the battery last with the fridge on and not charging? Once I get to my si...

The dealer just changed the power unit. I'll talk to them about it. Maybe they hooked up something wrong. It should not trip anything, but, if I am hooked up to a campsite, my breaker for it should pop.
It might be best to just use propane till I get it checked out.
When you said your dealer just changed the "power unit", do you mean the power converter and or the breaker box that it goes in?
If that is what you mean, there are 2 kinds of white wires in the converter/breaker panel box pending what color your TT manufacture uses.
If they are using white for 12 volt DC negative (common) and they are using white for 120 volt AC neutral, if they accidentally put a white 120 V AC neutral wire on the 12 volt DC negative grounding bus bar, it will then trip the GFCI every time. This is a somewhat common mistake but they should of known better. If this is what they did, they are tying earth ground to AC neutral by accident and that will trip the GFCI. It will not trip a circuit breaker as the AC hot is not involved.
In a camper, the AC neutral and the 12 volt DC negative are to be totally separate and shall not touch each other. And the AC neutral should not be tied to earth ground inside the camper either. Basically your camper is viewed as a real big appliance to the electric code. AC neutral and earth ground are only to be tied common inside the main power panel of your home.
As was said, if the fridge electric element has a leak to earth ground in it, it can trip the GFCI too. In most fridge compartments, there is a 120 volt plug connected to a wall outlet. Just unplug it and see if the GFCI trips. If it does not trip, then you have a fridge electric element issue. If it still trips unplugged, then the element has nothing to do with the GFCI problem

It is a bit confusing, but I'll help clarify things.
Where all the power goes in AC and DC, and what charges the batteries in my trailer is all one unit. It is one of my many "magic boxes".
I am writing this as I sit in my trailer at provincial park. I have this thing lighten up like a Christmas Tree. I have had no issues with it yet.
As I am not overly comfortable messing with electricity, I will contact the dealer when I get home and get them to look at it. Might be the power box. Might be the fridge. Might be something I am doing wrong. Might be something else entirely.
On a side note, they installed a new tank indicator and for some reason, the fresh water tank reads empty and the grey water tank is full, when I know the reverse is true. (in other words - it is going back to them regardless.)
