This is a one off idea i am having. To me my Skoolie doesn't have to have a totally self contained charging system. The expense of soar is steep but getting better.Gen sets are expensive and noisy. I have a 92 Geo Tracker . 96-and later 4x4 low mileage Trackers can be purchased for easy $2 grand.They tow just fantastic and yes there are Trackers and Suzuki Sidekicks that have NO rust. These 4 cylinder 1.6 engines get easy 23-27 MPG at 65 mph. Stock they have about a 45 amp alternator. A $24 Bracket gives you the ability to install a 1 wire GM alternator of any Amp you want.I will use at least a 95 Amp. I even have room to put another alternator on the drivers side .
Around here we have lots of ice and some very cold spells. Very common to start your vehicle and let it idle an hour or more with heat on to warm it up and melt the ice. Why not use this time to charge batteries? I understand it will take longer that that to charge 4-6 deep cycle batteries.
What drawbacks are there to this? I mean electrically? Engine wise?
