I think the approach to this problem as stated by Mr. Anderson is all wrong, in retrospect.

His Tech-Link deal has a built-in feature which indicates when it is time to buy another coach. The light, when blinking means: Buy a slide coach, buy a slide coach, buy a slide coach.

It's an automatic feature which has no manual override and is a built-in MPD dosing function.

The good thing here is that when you get to 5 buses, you can get a fleet discount on insurance and tires.

Good stuff.
