Flood Damage Query

I think I'd become the insurance company's most frequent caller, asking them what is the protocol for flood-damaged RVs? They might be willing to pay for a cleanup if it's required rather than totaling the unit. At the very least and since you mentioned the underbelly got wet, everything underneath needs to be pulled out and dried out. If water got into the underfloor ducting it needs to be drained out and purged, and at least the insulation, if any, needs to be replaced. Hope your insurance covers you for inability to occupy since you're full-timers.
