Thanks for the responses from everyone. Still waiting for Miller Insurance to get me an answer for any company they have that will write this type of policy, (I have been with them for years and have fulltimers coverage) Yes, you would think that it would be easy to find an insurance company willing to take more of your money. I am in Texas and apparently there were more companies but they have stopped writing in Texas.
I have been able to locate 2 with the recommendations of current residents, Texas Farm Bureau and Hochheim Prairie. The bigger companies I I have contacted can't understand the situation so they just say no, USAA is not available to me.
I guess I have the wrong information on the Co-ops being the same, eg. Timber Valley in Oregon, this co-op seems to be different.
So at least I was able to find a couple of companies (so far) who will write a policy, I was still hoping to hear from other Escapee Co-op owners as to who they are insuring with.
Thanks everyone.
