Most systems (including Blue Birds) are set up with negative ground, so if you remove the negative cable, then the batteries are guaranteed to be isolated.
Presumably, if you disconnect the positive cable, you get the same result, but if the disconnection (by a switch, for example) isn't complete -- if something is 'tapped' before the switch -- then the disconnection is only partial.
If there is a short from a positive wire to the frame, with the negative disconnected, then there is no fire. So the negative is the 'safer' wire to disconnect. (Of course, if there's a short, you'll find it rather quickly after hooking the battery up, again.)
This is all reversed in a system with a positive ground.

Pete, It may have something to do with the flow of electrons. Contrary to popular belief, electrons flow from negative to positive.

When disconnecting batteries it is always best to disconnect the ground side first. If you happen to hit a ground (frame, body etc.) with the wrench you won't get a spark.

Don, when I was in Ohio last year. I had to replace my old Trojans. All I could find were Crowns. They work great. I sold the coach and the new owner has not mentioned any problems with them.

I believe you will find Crown about the same as the Trojan, and their pricing is about $5.00/battery less comparing the T-105 to the Crown 225. http://www.solar-electric.com/cr225am6vode.html
