If you are relating to MH's then good maintenance with records are important. Low mileage is not necessarily a good thing (or bad). Mileage only reflects on the power train and not the overall use or condition of the MH. Usually the nit pic items will be out of the way with a used MH, and most of the major items will have been taken care of at the time they happened, but there is no way of predicting future major problems regardless of mileage. Certainly the depreciation will help make a used MH more attractive and depends on how long you plan to keep it.
