Agree with what Richard says above perhaps
Suggest you put a current meter in series with the battery positive terminal, report back the current drain. Its the only way to confirm current draw. We had one member who had a positive cable chaffing on the chassis and a resulting burning smell...don't want to scare you but its certainly worth investigating.
