Where can you find a new copy of the manual for your old RV? Regardless, there may come a time when you need your old RV owner’s manual but you don’t have it. If it’s a new RV, it probably came with the manual, but maybe you tossed it to save on weight or perhaps you’re on a trip and need it, but you left it at home. If you purchased the camper used, the previous owner may have thrown it away or misplaced it. When you purchase an RV, one of the items that may or may not be inside is the owner’s manual.
