One of the problems with buying a coach that has "deferred" maintenance is some corrections can be made with no future ill effects. For example replacing out of date or tires with sidewall cracking, replacing leaking shock aborbers, or leaking air bags instantly restores that portion of the coach. No harm, no foul.

But we cannot defer coolant changes, air filter changes or oil changes for example because replacing out of date items such as coolant and engine oil does not erase the harm that has already taken place. So a knowledgible buyer has no choice but to assume if a seller has allowed some maintenance items to be postponed, it is probable other items have been postponed. Delaying or even missing lubes can never correct the wear or harm done and that damage may not show up for a while. but when it does it can get expensive. Defer replacing bushings in an IFS front end and it is probable the ball joints will become damaged. Now instead of pressing in a few $50 bushings and paying for a few hours of labor it might ramp up into a $2000 repair. All of these types of deferred maintenance items will never be immediately noticed, but the damage has been done.

I would hope nobody believes doing a full maintenance on a coach that has a poor or no maintenance history does not all of a sudden create a great coach. I know a lot of buyers take pride in posting how the dealer or seller did this or that, but that is only a valuable maintenance event if it is a continuation of a good maintenance program
