Did you look around the fridge? Usually very close. Could be underneath.

What is it you don’t have? 120 vac? 12 vdc? Both?

12-volt DC fuses are commonly located adjacent to the 120-volt circuit breakers behind a small plate held in place by a thumb screw.

i only have it hooked up with the extension cord. no battery connected. I can't find a breaker or fuse box anywhere. thanks for the responses

I have no idea where to look. But I would start looking inside the trailer in the general area that cord comes in.

If you can post some pictures of the interior (have to use something like imgur or other photo hosting site) we can look and maybe spot the breakers.

I just looked at a few youtubes for your trailer and I think I have to agree with you. There is no breaker or fuse box in your trailer.
