Expert Reply:
If you are connected to a 30 amp shore power service and some things are not working on the trailer then the trailer may require a higher capacity service (probably 50 amp if that is the case) or there is a problem with the transfer switch and/or fuse panel. To diagnose those problems you would need to take the trailer to a dealer that works on trailers. If the transfer switch is not providing the AC power when connected to shore power then that would mean everything is trying to run off of battery power.
