nothing will work off of the battery

Get a cheap meter and verify fuses/breakers/grounds are good .
Hard to tell sometimes just looking.
Good Luck, Mike

Do you have a main shut off switch? With our fifth wheel, up behind the slide components in the side battery box door, is a switch. This same thing happened to us after getting it back from the dealership for some mods, and they had forgotten to turn this switch back on. I couldn't tell you where exactly it is, but you probably have one. Check your make and model online and you can get a wiring schematic that will point the exact location out. We found our schematic online and now carry it with us for this purpose.

In your battery compartment do have any 1" square looking relays. If you do then feel underneath them for a reset button and push it back in.

Check for a blown fuse in the converter.

Good suggestion. In our spring inspection, we found that everything worked but the water pump. We thought it was burnt out because DH said that in the fall, he came in and found that the switch was left on after we did the blow-out and winterization. Well, we thought for sure we had to replace it. What we found instead, thanks to a similar post on the Heartland forums, that the fuse was burnt. Replaced it and it worked!

I would get out my test meter and follow the power. The problem is where the power stops.

many Rockwoods have shutoff switches .... most are push/pull type .... since checking one isn't mentioned in the opening post, it might be wise to look of one
