I belong to a motorhome club for a now obsolete motorhome, and about 15 years ago one of the members took it upon himself to make a new updated service manual that covered all the mods as well as regular items....He wrote manuals for aircraft for the military for a living so was well experienced at it. It was probably 2 inches and in loose leaf form. He did in alone with the help of his wife and I think probably all 500 members of the club purchased one at $50.00 each. It is THE Bible of that particular motorhome and although he is gone now, it is still very much in demand. This was a long time ago and nowadays the ONLY way to go would be on a CD I would think.
