No power in my trailer with batteries

I went and got my trailer out of storage with my husband on Sunday. We hooked up both 12v batteries, in parallel. The batteries are fully charged (we double checked when we got home) and we are positive they are connected correctly. So we go to lower the tongue to hitch her up and no power, no lights inside either. We then hooked up the electrical cord to the trailer and everything works. For some reason the trailer is not getting any battery power. We checked the circuit board, tripped them, checked fuses, even found a hidden fuse under the tongue, but that was fine. Any ideas of what to do next? Is there a fuse box hidden somewhere for the converter? I took the panel off and saw nothing there. Maybe there is another fuse box hidden somewhere that I don't know of. My trailer is a Wildwood X-lite, 2015 - to young to have problems. Id appreciate any suggestions. Unfortunately I can't get her in until next week and I'm leaving Thursday morning.

Was the trailer stored outside with nothing covering the jack?

There are two 40A fuses to protect the convertor in case you hook up batteries wrong. Check them.
Do you have a battery shut off switch?
try using only one battery. RV manufacturers us weird color codes on some DC . Follow the wire you believe is ground and make sure it is ( connected to frame).

This often happens when new owners reinstall the battery and reverse the wires.
This either blows the fuse or trips the silver resettable fuse / breaker that is tucked up along the A-frame. It has a tiny black button that you press to reset.

Same problem

Just had same problem with my new FR Nitro. Found a bad circuit breaker under a plastic cover by my battery. Breaker had continuity but no voltage through it. I crossed the poles with a small screwdriver and my power came on. Replaced the breaker and no more problems.
