my grandfather bought one new in '73 and kept every piece of paper it came with plus every reciept for anything he ever bought from it. i eventually inherited it and when it was time to upgrade, the papers went with it. something i remember was that you NEED a battery to use the converter. the newer campers don't need one to convert shore power to 12 volt when plugged in but the holiday rambler's coverter would burn up if you plugged it in without a battery. it towed terrible with anything other than bias ply tires. we tried different lt's and st's and it just didn't matter. the water is on a pressure tank systems. there are some benefits to that system but to me it was easy and cheap to switch it to a plastic tank with an on demand pump (which also removed the metalic taste from the water.) every fall we would re paint the roof seal with aluminum roof seal... it was a great camper.
