Re: Park Model RV's
Most states have a 'personal property tax' that applies to moveable dwelling units - mobile homes, house boats. The devil is in the details as written in various state tax laws.
I suggest you don't focus on property taxes, but look at your cost of housing as a whole. Add together all the pieces (property tax, insurance, maintance, transportation to and from the places you frequent). Consider depreciation as a cost. RVs and mobile homes rarely pencil out if you need residual value.
