Tell me this. Which water heater is more likely to fail? A new one or a three year old model? Which Air conditioner is most likely to be more efficient and reliable? A new one or a four year old unit? Which wheel bearings are going to fail sooner and ruin a vacation? Those hand packed by a skilled mechanic with the recommended lubricant or those serviced by a owner who thinks that "one grease is as good as another and I am going to sell it anyway"? People do the strangest things when they are going to dump their used stuff.
After forty years in the construction business, we always preferred to know the service life of a unit and therefore purchased new when dealing with critical equipment like backhoes. Fresh paint and a new set of decals only fools the unwise.
The flaw in this logic is most RV's die of old age not system failures. It's nothing for an Air/Con or water heater to last the life of the unit. If you grease the bearings, axles are the same. There might be a small statistical difference but nothing close to enough to cover the depreciation costs.
This is different from construction equipment that dies from being worn out thru day in day out use.
