Hi Mary! Welcome to Permies.
I'm not a homeowner's agent, but I am a homeowner's adjuster.
You're definitely right in wanting to insure your property. If it would be a financial problem for you to have the house destroyed, then you should take steps to prevent that problem.
As far as carriers, it's going to be hard for anyone to help across state lines. Even the national insurers are forced to behave differently from state to state, because they have to adapt to each state's laws. Nationwide Ohio and Nationwide Indiana are different, for example.
So the best I can tell you is, call lots of them. Call the small insurers, call the large insurers. Call independent agents, call captive agents. Call lots of them.
There's no way to predict who wants to insure a place like yours, but
somebody does. Each year, they make plans. Some of them are saying, "You know what? We only want big houses in medium-sized towns. This year, we're going to give them better rates to attract more of them, and we'll use whatever excuse comes up to have fewer of other types." And other ones are saying, "Nobody wants to insure mobile homes this year, that means the rates are going to get sweeter, let's pursue mobile home owners." They all shift and churn. They add this type and drop that type. Somebody out there wants brand-new, eco-friendly houses. Not the first two places you tried, evidently, but somebody does. Keep calling till you find them.
Good luck!
