Battery issue

I am currently at a race with our 27RR with no hook ups. I have two deep cycle batteries and have been using the trailer since March with no issues.
Arrived two nights ago and used all battery power with the exception of using the generator a few times for the microwave.

Ran the ceiling vent almost continuously and after 24 hours the lights were dimming and panel showed batteries almost dead. Ran the generator for a few hours but as soon as I turned it off batteries were completely dead.

Being we are at the race I don't have a meter to check anything. All fuses look good. The new batteries had run dead last week but brought them up with shore power.

Anything else I can check? Where is the inverter located on my unit?

Thanks in advance.

Charging off a generator will require a better charger than the convertor that is built in can do. A high amp quick charge battery charger is in need.

Back home now. Continued to run generator today, did not charge batteries whatsoever.

Items run off of DC were not working when plugged into tow vehicle. Plugged into shore power at home for a few hours, when unplugged DC items would not work either.

Interestingly enough, electric jack worked just fine, so batteries must be charged but no inside will work off battery.

Any ideas?

Check the two high current fuses (30-40) in the converter and the resettable breaker on the frame near the front

Jack is wired direct so battery is up. Check resettable fuse on A frame. Also fuses on power panel

My power was out (a 26DBH) a few weeks ago. The breaker (under the am frame) had tripped and caused the same results you had.. Power when plugged into house or truck. Nothing on battery. A push of the little tiny plastic detent and I was in service.

I'm really striking out here. Can't find any type of breaker under the A-frame. I have a junction box, but when opened is only spliced wires.

Checked all 15 amp fuses again, and two 40 amp and all is good. I must be missing something obvious.

Here's what I got;

Look closely at your pic, at the breaker where the wires come together. There's a small black button you may need to push in. I can see it when I zoom in where back and red wire is connected.
Edit. Meant black wire.
