We just bought a 1996 Gulfstream. It's a 24 ft Innsbruck. We did not get any manuals with it and need help. We are having a hard time finding the water drains to get all the anti-freeze out. We want to run water thru it and get it ready for hunting. I got the general manual off line, but we can't tell where the drains are. Will there be anit-freeze in the hot water tank, fresh water tank ? No idea !! Thanks for any help we can get.
