I meant to update this discussion but never got back to it. In a nutshell:
- Our auto insurance with Safety (a Massachusetts company) will cover the trailer only when it is attached to your tow vehicle.
- The only company that seems to insure (unattached) travel trailers in Massachusetts is Foremost.
- Our Umbrella liability policy will add liability insurance (up to $1 million, I think), depending on the amount of your 'Underlying' insurance. So to get the maximum we had to insure with Foremost for $500k. Cost: $479.
This is a very expensive state, in more ways than one.
But let us be grateful we can celebrate our Independence and freedom today, July 4th.
