I know there should not be a power drain, the old one did not have a drain, but it disappeared from the truck mysteriously...the dealer, who is no longer in business, literally gave me a new one. The new models were coming out and this one was an older one like mine. This was about 5 or 6 years ago.
We thought we had a new battery (actually we KNEW we had a newer battery), I am afraid my son switched it out for his old one. So Hubby bought a new battery today.
With a new battery we do not have a problem unless the truck sits all winter.
Bottom line is hubby is going to make me unplug the prodigy every time I am not towing. Maybe I will make him plug it in and unplug it
