Depreciation Guidelines?

I don't know but I think it's pretty difficult to estimate the amount of depreciation very accurately. To go from $200,000 to $98,000 seems pretty extreme to me but not impossible. An RV is only worth what a buyer will pay at any point in time so it could vary a huge amount. For example, if you try to sell a year after purchase, how long are you willing to hold out for a higher price. Or you might get lucky and find that 1 buyer in the area right away that really wants the unit. You might not find a buyer at any price. It's not like a reasonably priced house or car in that there just aren't that many buyers for such a specialized item. The only thing I know for sure is that RV's depreciate a lot and that's the single most expensive part of RVing. If you have to worry about it too much maybe you can't afford it.
