Parking in a persons garage for free for the next 3 months my wife says we need a total new kitchen . Carpenter needs our two car garage for his tools etc. hard winter here now . I have access to the truck which is about 7 miles away but we really only need one car so I will plug the trickle chargers in and lock it up. How often should I go take it for a drive and how far . Anything else this is new to me?
