Insurance (RV & Contents) - 2010 Keystone Fuzion 5th Wheel

We are selling our home and planning on RVing full time. In recent discussion with our auto insurance carrier, insurance coverage for our 5th wheel trailer extends from our vehicle coverage, but will not cover our contents.

We are told the only way we can get coverage on our contents is through a homeowner/renters policy which we will have neither. Welcome thoughts or how others have handled this issue!
