I need advice on my totalled yet still beautiful baby.

Strange situation you have. I'd be seeking professional advice – second opinion on the RV and likely at least a consultation with legal council. Remember, if you decide to take the insurance co to court things change – and get drawn out. Were I in your shoes I'd be worried about being SOL and as I said looking for professional advice. BTW - you can hire independent adjusters to review your claim and help battle insurance companies. Of course professionals cost.

I know it sux, but make sure you step back and realize when it is time to cut your losses. Legal cases can be very costly (as you likely know) to the point where its just not worth it. If the offer you a settlement consider it while looking at units you can afford, if thats even an option. Personally I'd rather be camping with my boys in a older, smaller but clean unit than not at all.

Hope my rambling can help.
