The last time I ran everything was in the fall and I've kept the TC plugged in all winter so I'm hoping the batteries have been keeping a charge good. So how long of a drive does it take to charge the batteries would you say? When I started the truck though the truck batteries and everything should have given off enough juice though to work the jacks even if the TC batteries where dead right? Thanks for the help and I'll take a look at everything when I get home just trying to get an idea of where to start to make it go faster and make sure we can have heat through the weekend.
