Hi, I've just purcased a 1988 GB Cruise Master LM 28 ft. long with the 460 engine setup. I was wondering if anyone would know of a website or where ever for me to getting a copy of the manual for this RV. Everything works fine on it however I am not well versed in the operation of the goodies on this thing, multiple holding tanks, electrical hookups and such. Basically I'd like to know how everything is supposed to work so I don't goof anything up. Any help would be appreciated, thanks.....SE Michigan
