It sounds to me that the electric jack got it's power from the Tow Vehicle, and that the time driving did not charge the batteries at all... or... the battery is actually charged, but the battery power is not running to the 12 volt panel (more likely).
If you know your battery is good, but still nothing works.. then...
The way to really check this is to use your jumper cables and a short piece of wire. Put the short piece of wire into the negative of the 12 volt panel, and connect the jumper cable from the other end of the short piece to the negative terminal of the battery. Did it work?
If it did not work, put the short piece of wire into the positive side of the 12 volt panel and connect the jumper from the other end of the short wire to the positive side of the battery.
Most likely, one or the other will fix it and you will know where to look from that. If neither seems to, hook up both sides of the panel to both sides of the battery.
