Plenty of room for all types, from the roll your own crowd to the tailor mades, and all shades in between. Just so's no one is so snooty they cant stand being anywhere near the other.
We are singing from the same page in the hymnal. I have belonged to the Prevost Proud and the Converted Bus chapter of FMCA and found I didn't fit in either. The Prouds seemed more interested in my balance sheet and the Converted Bus folks seemed to think I wasn't qualified to belong because I drove a store bought bus.
But except for those instances I have found if a person talks "bus" he fits in with every group. There is very little on my buses that I haven't repaired, replaced or improved, from the entire Prevost chassis to the converter side. I have rebuilt my 8V92, changed the entire undercarriage from air bags to Norgrens to brakes (chambers and friction). I have redone floors, reupholstered the furnishings and modified the way the converters built the systems and bays.
But I never really felt I fit in with either group because I'm not in a position to stroke a check for a new one, nor do I want to dedicate the time to start from the beginning to build one.
I find the comments and perspectives very interesting and I also find myself in agreement.
