When Irma came through Florida our Fifth Wheel Toy Hauler was damaged and We have SafeCo for all of our vehicles. So, I called in and started a claim. This RV was in a park about 30 minutes from our sticks and bricks so I let them know to please give me a heads up on when the Adjuster would be coming.
I'm sitting around on a Sunday Morning when I got a phone call from the adjuster saying that he was at the RV. I told him it would take me almost an hour to get there and he said no problem.
The area where the RV was at DID NOT Flood so the Inspector was having a problem with our "Flood" Claim. I told him the flooding came from a Roof Vent that had blown off during the storm which flooded the Galley Area. All of the area was soaked including the floor of the slide. He told me to get some estimates from RV Dealers for repairs. The lowest that I got started at $10,000 but stated that it would go up from there depending on what was found once the tore into it.
The adjuster ask me what I thought it was worth and I was honest as I had already checked NADA and also searched for recent sales of me model rig.
Long Story short, they totalled it and gave me way more than I thought I would be getting. When the Adjuster was there, he listed ALL options such as Generator etc, which he said made a difference when it came to the settlement price.
To the OP, I agree that you should get some honest estimates but something to keep in mind is the amount of time that your RV will sit before repairs are completed. This was a big worry for us as we were concerned about Black Mold. This was one of the reasons that the decision to Total it was made and something for you to mention to your Insurer.
Best of Luck and I hope they total your rig as it will most likely not ever be the same.
