New Motor Home vs Used

I notice that a lot of folks recommend against buying new due to the initial depreciation of the unit. However, I have reviewed quite a few brand new Class C's where the asking price is equal to or even below that of NADA. Yes, there are some where the asking price is outrageous and where I would imagine extreme negotiations are in order to lower the price down to a manageable amount. But, there are still many decent priced new units. Also, with a new unit, you do get the manufacturer's warranty and where you don't inherit any prior problems. If one is intent on keeping their motor home for quite few years then I don't think that depreciation would be a pertinent concern as the older it gets the less it depreciates. Are manufacturer's warranties transferable to a new owner wherein one could purchase a motor home a couple of years old and still be initially covered? Pros and cons please.
