We have recently purchased a 2008 Heartland Cyclone 4012. The camper is in great condition but the previous owner did not have an owner's manual for it. We have owned a motorhome for several years and found loads of valuable info on it in the manual. Is there any resource where we could find PDF files of the manual or can one still be purchased. The not all of the controls on this camper are marked so a manual wuould really be a great help. Thank you in advance.
