What's the difference between TDH-5303AC, T6H-5305A, and 5309A/10A? In general, how can I decipher those codes? I fondly remember the 52XX series.
What was the deal with air conditioning on those buses? Blitz installed new air conditioning, no? In my experience, it was rarely if ever used. (Come to think of it, didn't the buses come with air conditioning originally? That was never used either.) In their last years, I vastly preferred the Blitz rebuilds to the RTSs -- except in the summer.
Were any of the GM fishbowls not rebuilt? Of course, the Flx's weren't, but those were in pretty good shape.
