Simple example you pull up to pay a toll only to find out it's one of those very narrow toll booths. You end up clipping a mirror. That mirror will be made by someone, but who? No toll free number to call to find out. Hand it over to the bump shop and hope they can figure it out. Of course if you don't mind paying them to figure it out, no problem.
Another example, slide won't come out. Turns out there is a relay that is buried from sight. The tech support line knows it there and they know it's a common problem. The RV repair guy and you have no clue, but will find it sooner or later but you're on your own.
Maybe the used coach didn't come with a wiring diagram and your door handle doesn't light up. It's probably a fuse or some little switch, but the coach has multiple places to check and will take a half day to go thru them all. Would be nice to have a wiring diagram for the next time something simple like that goes so you're not wasting all your time chasing down a line.
The list goes on. Does that stuff stop you from buying an orphan coach of course not. Should you factor that into your overall price, I would.
Then how about those little decorative items on the outside when they go bad and start making that nice coach look like it qualifies for the 10 year old rule.....:B
Thereโs no fool, like an old fool.
