Tim,
It looks like you have one of life's most unenjoyable trials (literally) behind you now and one of life's MOST enjoyable trials (figuratively) ahead of you...selecting a bus.
Just remember, for as many members there are as many opinions. I think when you see THE BUS, you will know. Deciding to step into a Prevost conversion is the big one. Which converter, which accessories you should have, is like adding spices, only you can decide what you like.
I have never heard anyone on POG say anything like "I bought the wrong bus"
Best of luck searching.
