Check with your insurance broker about both your home and your RV coverage.
We have our motorhome parked in our driveway for the foreseeable and our daughter is going to move into it for a while. I called our RV insurance company “just to make sure” there wasn’t anything extra we needed to cover and they said our RV policy would be void if someone, even me, was living in it ... here at home. Drive it south and live in it for the winter - no problem! Logic, anyone...?
How’s the ventilation in your garage for fresh air?
