So she wants to visit her ransacked caravan, I do that, ad then she said the other ransacked caravan, I assumed it was durable dunns but nothing happened? Is ther another?

Yes, you'll visit 3 wrecked caravans in all, the first is hers, the second (griffin wares caravan) is located south-west of the horowitz farmstead near a silver rush billboard and the third is durable dunns.
