I think you are right concerning all the examples given with one
possible exception. Certainly, tires, belts, hoses (though the
waterboxer is unconscionably complicated), fuel lines can all be
monitored and r&r done as needed, and as one would do with any vehicle.
The head "gaskets"? I dunno. Certainly, since I've owned my camper,
I've done everything to maintain (and to make up for possible previous
owner neglect) the cooling system. But, the heads are now leaking. Did
the previous owner use the wrong antifreeze? Was the rebuild botched,
only 30K miles ago? Or is this just an inherently bad design, and will
leak regardless? Dunno. Dunno if rubber vs. synthetic vs. typical
metal and composite gaskets make the difference either.
