After reading this thread, I logged on to the main site to have a look at some of those brochures, and the year 1990 caught my eye, I was looking at the picture on the cover thinking " that looks like a Prevost" and sure enough Beaver did make a Prevost bus conversion that year, I had no idea.
Steve , I know your pain when it comes to buying projects, you may have seen some of my posts as I have worked through the issues on the two Marquis that I have had, it's so nice when you get to the point that you can use them at least, now I'm doing the same thing with this Travel Supreme that I bought, I must be a sucker for punishment.
Just keep making lists and crossing things off, and eventually you will just be down to general maintenance.
