No power to trailer from battery

We have a Rockwood Roo that we picked up from the dealer yesterday after getting the Moryde steps replaced with Torklift steps. While on the dealer's lot, I extended and retracted both slides to check some other work they had done so the electric on battery was working at that time. When attaching the trailer plug, my husband accidently tried to insert the plug upside down. He corrected that but when we got home, we had no power in the trailer - lights, pump and slides won't work. Our battery monitor says 100% at 13.0v. The lights and slides work fine when we plug into shore power. The front tongue lift is working off the battery. All the circuit breakers are on, there are no burned out fuses inside by the circuit breaker and the battery disconnect is showing connected. Any ideas of what we can try before we take the rig to a shop; waiting weeks to get an appt and more weeks to get it back?

Try to find and reset the 12 volt DC circuit breaker. Hold on and I will get you a link that we keep in the FAQ subsection.

Please read this link:

If everything works on shore power, then the converter is outputting 12 volt DC, so your problem is going to lie in receiving power FROM the battery.

Check the 12 volt DC circuit breaker and see if it has tripped. It's location is explained in the link above

Check that battery disconnect is working correctly
Use a multi meter read voltage before and after switch

Then find the main fuses on the end of your main battery cables

wmtire's solution in post #3 is the most likely source of the problem.
