Hello folks
I am storing a 2010 Casita & truck at a friend's house for 6 months. The friend runs the truck every 4-5 weeks for about 5 minutes.
While traveling he told me the truck battery was dead. The 7pin cable is plugged into truck, and I do not have a battery isolator. The Truck battery is 2.5 years old, and the Casita's deep cycle battery is only 6 months. Assume nothing is on in camper (e.g. all lights are turned off).
1) Is there a steady drain on the 12V line (from the truck) from the charge controller or other circuitry in Casita? I know the LP detector runs continuous, but is this a significant load?
2) without shore power, should a camper be plugged / not be plugged into towing vehicle?
3) Recommendations: disconnect Casita battery terminal? Pull fuse(s)?
I am at a disadvantage of not being there to run some detailed tests (battery test, amp/volt meter) -- I can relay some quick suggestions.
Thank you for your help!
