I own a 1973, 23 foot Safari and being a novice with RVs, I don't know where to start looking for the right insurance for my Vintage Airstream. My insurance agent told to me that my trailer was covered under my truck insurance. I can only assume he was talking about some minimal level of liability. I am courious what you experienced Airstream owners recommend for coverage. Also, how do you place an accurate value on a Vintage Airstream for insurance purposes? I've not seen an appraisal book that goes back that far. Areas I believe I should be considering are:
1. Liability
2. Fire
3. Vandalism
4. Storm damage - Hailstorm, flooding
5. Damage from falling tree limbs
6. A Reputable Company - Who, where?
7. Cost

Are there other areas I should be considering? What has been your experience? I sure would appreciate any help you can give me on this matter.

Thanks,
Larry
